Ive had the parts for years uninstalled and i am trying to find the pinout so i can connect them and tune the maft. The bosch has the 2 white and 1 black does anyone know what i should connect them to on the afr. Thanks in advance!

Hey guys hate to do this but its time now.   Selling my car which has 97,xxx miles about 7,xxx on rebuild since. balance shafts eliminated, Amc Njv head with ajusa head gasket rebuilt bottom end, A/c and all of its components have been removed. Runs great starts up every time mechanically sound. No over heating. Has 83 hood also have vents but haven't put them on. Has mods such as 1g mas mod, 1g hard pipe, 3inch exhaust bolt on from jolyrgr will include stock exhaust for smog purposes as well as

I have pulled the diaphragm from the distributor, and after inspection I find that once pressure is applied to it, after releasing the pressure it takes an incredible amount of vacuum to get it to advance again. It pops to full advance, like something is sticking but if vacuum is applied without adding and venting pressure it functions as a normal vacuum advance would.   My question is this, is there any way to fix this or should it just be replaced?

Took off the manifold and I have to replace 2 of the studs. Anyone know the thread/pitch/length?
