Was the pulley spacer for the smog pump the thick or the thin kind.
Second question.... Were the pulley's only gray phosphate or were some painted. The one I had was painted, I did not notice it ever being gray phosphate.
If anyone has any spare 68 smog stuff hanging around, let me know. I pretty much have everything for a small block system but some stuff might be better looking. Probably need some tower clamps. I could use the nickel injector thingys that go down into the manifolds.
I need a black plug for the pressure relief valve. I have a white one if someone wanted to trade. Thats another question. Where all the pressure relief valve plugs on the pump BLACK? I have seen white but that might have been someone making due or the pump was swapped out. I mainly see black on Big Block set ups. White was used on a lot of camaro's with similar engines.
I once looked at a pretty original 69 big block car and saw 1 1/8 inch tower clamps on the hoses. But, I have mainly seen 1 1/6 inch tower clamps. Any opinions appreciated or observations.
