Stop in for a cup of coffee

Johhny you would know do the advance bushings from a msd the same as a GM?
the BIG hei doesnt share much in common with the GM hei. the "msd" and my clones use the same stuff, and they are usually 6 packs of completely round bushings, no "shelf"
let me see what i can find. probably have some in the garage. whats your timeframe?
