Need a few ignition part numbers

[chev4life]

I am having a few idle stumbling problems where I can see twiching in my tach and it only happens after the engine has completely warmed up. I think it is down to my ignition module and ignition pickup that are causing the problems because everything else is relatively new. Can you guys help me out with a few AC Delco parts numbers for these or a place I can find them? Thanks.

Before you start replacing the more expensive parts, take a look at some of the easier stuff like the pivot bushings on your mechanical advance weights. When these little buggers wear out the allow the advance weights to flop around on their pivot pins and WILL affect your idle and can cause stumbling as you tip off idle.

The replacement bushings are cheap (NAPA part # DP112 - less than $4.00) and they can make a world of difference.
