hi
authentic classics sells refurb'd drums and shoes

I think K&K does also.

most likely they are on a core exchange basis.

or you could send your drums and shoes to J&G brake drum relining. 
 I sent both sets of shoes and drums for my 66 to them for refurb.  total was just under 1K.

if you do sen them in, be sure to include a copy of the Bbb page showing the correct dimensions and thicknesses.

awesome advice and references. i knew about k&k and have bought from them in the past, but they have only a used one for >$1k. i found a set locally for $600 with enough meat on them to machine to spec. for anyone reading this in future, yes steel will fit (eg. from a ponton), but aluminum is correct for SL (ponton also has an aluminum part number as i listed above, so ponton had both steel and aluminum, and our SL's only used aluminum - now you know). the reasons are a) weight and b) heat dissipation.  the Big blue book says new, they would be 230mm ID and you can machine them down only to 231mm (or 6.060 and 6.090" respectively).

If steel you could go another 1mm, but steel isn't right for the SL (although it would 'fit' it is not recommended).

book-marking jgrelining. thank you!

They're cast iron, but I'm sure that everyone knows that.

I have quite a selection of all types used ( aluminum finned, steel finned and steel no fins). I prefer the aluminum finned for being light weight and better cooling. I used aluminum finned all around on my 190SL even though it came with steel finned when new.
