First of all, how are you going to attach the z-bar to the engine?

Is this the fork that you have now?



Post some pictures. What exactly is "not lining up?"

Andrew

Mr5.3cammedup

Pretty sure this is the part number you need for your application.

Do a search with this #.

That picture I "borrowed" from Pace Performance I think...if I remember correctly they wanted like over $40 bucks...

I think Summit/Jegs has them for under $20...

Google that part # I gave you, there will be lots of places that handle it.

If you search a little, I'll bet there are vendors on this site that will have what you need.

It's nice to support them.

Tamraz, opgi, the parts place, year one, ebay...
you need the bbc 168 tooth version for the 621 bellhousing, not the sbc 153 tooth version.

Mr5.3cammedup

Thanks Gary68 and CattleAc for helping me out ordered the clutch fork from the parts place today BUT they dont have that throwout bearing with the 1.25 diameter and part store here in my area dont have it either
Do yall have a part # for the throwout bearing?

1.25" is the depth of the throwout bearing. Trust me, they have dozens of them in every parts store in the US. It's the most common one used on GM vehicles.
Just have them look up one for a 70 BBC chevelle, same as the fork, about $12.

Mr5.3cammedup

**** i asked them to pull up one that compatible to the 1050 flywheel 84.99 what they told me
that was o reillys
then one had like a 1.248 but will double check tomorrow

That sachs flywheel is used in 1999+ trucks. They use a hydraulic throwout bearing. You need one that works with the 621 bell, fork, and z bar.
I just looked up a 70 chevelle, 454 release bearing on Rock Auto, $13.
