T56 question

I have everything I need for the swap, minus a few things. One: my torque arm and crossmember, which are back ordered, and two: The clutch fork.
As far as the clutch fork goes, I thought I read something about a piece that goes along with it. Or does it just connect to the throwout bearing? I have the clutch disk, pressure plate, throwout bearing, flywheel, and hydrolic assembly.
I am pretty unknowledgeable when it comes to trannies, so please for give me. Thank you in advance

If it does, then I guess I'm in luck. What does it look like and how could I tell. I took a look in the 93-up haynes manual, and it showed a clutch fork, but I may have accidentally been looking at the v6 5 speed. Can anyone tell me for sure. Thank you, Roy

Are you talking about an aftermarket T56? If yours isn't aftermarket, you don't need a new torque arm, just a crossmember. All 82-02 camaros use the same size torque arm, so unless you went aftermarket, your old torque arm is fine.

As far as the clutch fork, yes it has one. The slave cylinder pushes against the clutch fork, which is what pulls the throwout bearing.

Wow, that's news to me...seeing how my '82 came with a TH200C trans which is ~4 inches shorter than a TH700. Holding the torque arm from the original setup next to a later-model 3rd gen that came w/ a TH700, there's about 3-4" difference in length.

Might want to check your facts before posting an error and throwing some poor guy off track.

You can reuse your original driveshaft and torque arm IF the tranny is an OEM t-56 (From a 700R4 or T-5).

The aftermarket t-56 uses different length torque arm and driveshaft.

Afternmarket t-56 uses a conventional clutch while the OEM needs the funky backazzwards setup.

An LS1 OEM t-56 has no clutch fork, an LT1 does.

You will need the torque arm mount off the T56 tranny as well. The mounts are not the same, and you can't put your's on the t56.
