Hydraulic Clutch

[Texasbigblock]

Hi all,
I’m a 67-72 guy but need some square body help this time. I have a 1970 Chevy body, that I put on a 1985 dually chassis. I’m using the hydraulic clutch setup from the 1985 (trans, slave, bell housing, fork, etc...). I’m using the master from an 88 because the earlier models had an angled master that was more difficult to mount to the 1970 firewall. So the master is 1988, but everything else is 1985 stuff.
I have read tons of posts on how to bleed these and I’ve successful bled these before on different trucks. But, after many attempts, on the truck and on the bench, I still have no pedal. With the engine running I can’t get the truck into gear even with the pedal to the floor. I feel very little resistance from the pedal except right at the floor. When the clutch is held, I can go under the truck and it appears that the push rod on the slave is fully engage with the fork (I can’t move the fork AT ALL by hand any further.

Also, this shouldn’t effect my current issue, but is there supposed to be any kind of return spring on the clutch fork?

Any thoughts?
Still air somewhere?

I’m starting to miss my manual clutch.
