hi,
so after reading other posts on tdc, i went back out an looked for the slash on my old disti.

ended up rotating the 123 180 degrees.  now the rotor and #1 line up.

Sometimes it's more convenient, because of the ignition wire length and vacuum port location, to rotate the distributor drive instead.
