Hey Cobalt 327 and American Muscle, thanks for the info. I uploaded an image of what the original distributor had. Itd be the grommet with 4 holes going into the CM. But I threw in the dizzy from the original '75 350 we currently have in the truck. HEI, but with out the electronic carb set up. Its an '84 A.M, long bed. Nothing HP, just had the rebuild shop throw in flat top pistons and a better than stock cam. Still cant wait to drive this thing to the beach and do some fishing! going on a fishing withdrawal.
