A frame up restoration presents numerous decisions including many that share the topic, "Refurb the original part or replace with a new one". Of the many choices I had to make on my recent project, one that stands out in my mind as clearly the right choice was to refurbish the firewall pad rather than replace it with new, aftermarket material.
Fortunately, I was lucky enough to have original material that was capable of refurbishment. Encouraged by my restorer, we elected to salvage the original pad. It was carefully removed, the old backing scraped away, new backing pad was cut to fit and applied to the face 'skin', then a light coat of flat black spray paint finished it. Sure it took longer than replacing it with new material, but the visual result is very gratifying.
While my engine bay is by no means perfect, the opportunity to retain this very visual component was fortunate. All of this said to encourage those who may be entering a restoration to carefully assess the firewall pad and reuse it if you can. I believe it to be one of the small but significant successes of my recent project.

Very nice job! It is indeed good that you were able to rescue the original pad. I like the look and texture, wonder why noone has duplicated it, or at least noone currently.

Ed,
"...engine bay is by no means perfect"? If that's the case, I could never post pics of mine. This one looks fantastic!

Wow, your car looks amazing. Congratulations.
One question, are you keeping the new style brake fluid reservoir or going with the original type? The only reason I ask is that I recently faced the decision as well and opted to go back to the orginal type.

Looks very nice indeed. I agree it was well worth the work of keeping it. Why is it that the original pad looks sooo much better?

Ed,
Very nice job on the restoration. You were very thoughtful on the firewall pad. Wish I had known that the original material was not available before I replaced my pad.
Best,

Ed, the engine and its compartment look great! The only thing I see that's missing are the plastic clips that go along the ridge above the firewall pad. Outstanding job! :D

Hey Ed,
Nice Job
I re-used one of your pics to ask a question?

Bob, if you are talking about that brass springy thing, I always assumed it was to maintain ground/electrical continuity with the bonnet closed?

Ed,
The engine bay looks terrific. You want to make sure to cant the antenna back to an angle that's almost parallel to the windshield. That's one of those unwritten details that was taught to me by a retired elderly Becker dealer from back in the day. That's how they were instructed to do it.

Ken:
With regard to the brake fluid reservoir, the car currently has a new one installed but I definately kept the old one as I saw that part in particular as one I might want to switch back to original at some point. Not unlike the firewall pad, the new reservoirs don't really match the original look so I've left myself with that option.

Why would you need to "maintain ground/electrical continuity" with the hood? I think the springy thing is there to keep the hood from ratteling when closed and pop the hood open.

Hey Michael,
Yeah the semi-circular copper/brass spring thing on the hood latch unit.
Were they on all Pagodas?
I don't have one on my car and I don't really see the need for one.
Is it to do with static electricity or radio interference?
How is it attached to the hood latch?

Norton,
I didn't suggest why one would need to have this continuity, only that my experience with these things indicate that that's what it looks like. Unfinished spring brass is generally used for electrical continuity in moving parts. Why is a question for an engineer. If it were just springyness one was looking for there are better material choices then spring brass, but who knows? Most old American cars do have a spring in the same general area to pop the hood up and prevent rattles, but they are generally big steel springs. Maybe the aluminum in the hood only needs a gentle brass push? I guess the questions to ask everyone is who has it and who doesn't, and whose hood pops up and whose doesn't, and whose rattles and whose doesn't?
BTW, I DO have the piece; my hood does pop up with authority, and it does not rattle. Many other things may rattle, but not my hood!

Hello,
Maybe these were installed on cars which came from the factory with optional radios? Mercedes installed "static ground straps" on the hoods of sedans of the era for this purpose. They prevented static electric interferance in the radios.

I just checked mine and there is no brass springy thing (love these technical terms)and the hood pops open just fine.

Right you are Joe, I was looking at the photo's and not my car when I answered. The springy thing could not have anything to do with rattels or popping the hood. Both my 71 and 68 have it, both came with radio's. The hood even has a matching peice to ground it, I'm dead wrong :?

Looking under group member's hoods on the group has been an education for me as a new owner of a W113. A couple of questions have arisen. While on the subject of pads, Is there supposed to be a pad on the underside of the hood? If so, my car doesn't have one. Also, on the top of the oblong bowl shaped front spring towers, I have seen rubber covers on other members cars. I don't have them either. This "bowl" looks like it needs a cover, and it looks very un-Mercedes-Benz not to have one. Set me straight, gentlemen.
The good news is that my wife and I made our longest trip to date in our W113, a total of 130 km today on a Sunday afternoon drive. My car has sat for quite a while, and after the drive at highway speeds, it just seemed to come alive. It's a beautiful little car and to have it run really well is a definite plus!

I wonder how many hoods will be opened in saerch of the "brass springy thing."
Guilty!
Jim, no pad on the underside of the hood. As for the plastic oval shaped covers this item was discontinued at some point during production. My car has these covers so I would guess sometime after 1969.

My car has a dealer installed Blaupunkt radio but definitely no spring-thing and no rattles.
The bonnet bounces up very energetically when the lever is pulled.
The underside of the bonnet was re-painted everywhere including the metal plate that spring-thing would make contact with.

The contact spring is for radio suppression reasons. The area it contacts on the "striker" plate should be bare metal. It has nothing to do with opening the hood - it is too weak to perform such a purpose. The little spring loaded rod just forward of the hood latch proper is what raises the hood. It was part of every M-B hood latch until the W202 if I am not mistaken.

I believe the rubber/plastic covers for the shock towers in the front only were used through sometime in the 250SL run. I do not have the reference materials infront of me, but I do not think any of the 280's came with those.
Jonny B
1967 250SL Auto

I believe Johnny B is correct. The shock towers on a 280 SL shouldn't have the covers.
Vince is also correct about the radio suppression piece at the hood latch, however, I believe they were only seen on US-spec Pagodas.

As for the pad material, I would assume if someone had that diamond pattern material as New Old Stock in a roll, it would be rather valuable ; )

My Italian Pagoda has the radio suppression spring on the hood latch. Also, on the front axle grease caps there is a tab that contacts a point protruding from the axle. This is for radio noise suppression as well.
Quite a tangential journey from firewall pads to brass springy things!
