Also not sure what your SB one looks like but here is one I saved from a 402. I know this isnt the for sale board but let me know if you need it.

I got the one for my 454 from Auto Tire and Parts (Napa). It was a ball with a threaded end.

The way we mounted the engine we did have to move the mount on the frame to get a good angle.

The zbar from the SBC should work, one did on my BBC. The angle may be a bit funky as mentioned above. You may need a bracket or you may be able to use the threaded hole in the block. Its kinda one those deals you wont know till you get the engine and trans stabbed in there. Another Idea I kinda kick myself for not doing is a conversion to a hydraulic throw out bearing. Smoother clutch feel and elimantes the angles and parts. While I'm not a fan of LMC parts, their catalog has a great view of all the parts needed for the z bar set up

I bought the clutch ball that screws into the block of a 454 at Auto Tire and Parts/Napa for around $12. The item number is 615-1197.

Just thought this might help some one some day.

did it line up with the Z-bar?
