I will be buying some tune-up parts for my 67 350 (original engine) and was wondering the difference between AC Delco parts. They have listed on Rock Auto and the AC Delco website parts catalog two different p/n's for both a cap and rotor.
Caps listed: D308R vs C349
Rotors listed: C435 vs D426R
Anyone know what the differences are? I want to make sure I get the correct parts the first time. Thanks...
