Currently gathering parts in preparation for ZF6 swapping my 1993 auto corvette.
I have everything I need but can’t seem to find the recommended pilot bushing in stock anywhere.. anyone have an alternative part # or know where to find one?
I found mine on ebay. Thinking it was better than the bearing. After having issues with Bill's rebuild, I shipped him my car. Upon installation (Bill reinstall) of my zf6, he said the bearing is better than the bushing.
So, if you contact Bill B about that, he may recommend a bearing.
The fluted style is tough to find, that's what Bill recommended up to a time when they became unobtanium.
Prefer the sintered brass material, it lasts a lifetime, the bushing is impregnated with lubricant and it has a lot of lubricity against polished steel anyway.
Ended up with a Quartemaster bushing, as it was the correct dimension... I found some variances between bushings and bearings and crankshaft bore measurements, best to make careful measurements, so that press fit is in the 0.001 to 0.002 range, many were over 0.003 range (assuming perhaps worn out crank pilot journals). My new SCAT crank was 1.0913" pilot bore size, and used a 1.0930" bushing, and pressed in using a steering wheel puller to the flywheel bolts, as I'm not too fond of hammering on the crankshaft.

Yeah that’s what I had been reading.. so I was disappointed when I couldn’t find any for sale. I guess it’s time to finally buy seem micrometers !

Any thoughts on this bushing? #McLeod 8-1094-1, (Pilot Bushing: Bronze Oilight: GM Except Pontiac. 1.094" OD x .592"ID). Worth a shot or should I keep looking?
Reached out to Bill (ZFDoc), and suggested checking Jerry's Gaskets for the fluted pilot bushing I was looking for, and they currently have them in stock! Here is the link incase anyone else needs one. https://www.jerrysgaskets.com/bushin...lot-90-95-8b2/
I am not sure on that one. I know LT4s have different crankshafts, and Jerry's Gaskets lists the bushing as 1990-1995 model years.. I'm guessing that means the LT4 probably used a different one. But might need to reach out to them and see.
Need help finding pilot bushing!
