SL/R129: rotor and dist cap
Thanks again Peter
Benz has a diagnostic port, that requires a reader and counting flashes of light to examine the issues with less grease under the finger nails. I used a dealer ( then an indy, for most of the restoration) for all the issues with the M120 engine and the nightmare of an ecological wiring harness, but your 92 would not have those issues.
Good luck
