Never bled the clutch slave, is there a procedure for this somewhere?
Pilot bearing and throw out bearing both new.
Clutch adjustment well maybe that is the problem..
Synchros bad(I hope not)
I have not replaced the fluid , which type of redline oil do you recommend using? What about royal purple synchro max?

Couple of questions for you-

​​​​​​1. Did you replace the splined shaft?
2. Did you get the proper lubes for shaft, PP fingers and guide tube?

if your answer was no to either 1 or 2 you need to pull it out and get the parts and supplies and re-do it.

Since you have a lift here is an easy test to see if your clutch is fully releasing. With the the wheels off the ground, put the car in gear, have a helper depress the clutch pedal while you try to rotate the tires, if you feel resistance or can not rotate the wheels you know that the clutch is not fully dis-engaging. Of course you are doing this with the engine off.

My experience with a properly adjusted DD clutch, when you depress the clutch it takes about 1 to 1.5 seconds for the gears to stop rotating or at least slow down. Another test is to have the car running. Press in the clutch wait about 3 seconds then put it in reverse. If it grinds, your clutch is dragging.

​​​​​After all of the posts I read about DD clutch adjustment I was less than confident in getting it done, but once I had good replacement parts, everything cleaned and lubed, I nailed it on the first try. I don't think it's as hard as it's made out to be.

Yes to 1 and 2. But what are the PP fingers?
I will test the clutch as you described.
