Does the crossmember have any adjustment options or is in a fixed position?

Are you asking about the crossmember the transmission mounts on and are you asking because you are swapping in a different transmission with a different mounting pad location? If yes, there is no adjustment for the fore and aft position.

Your options are to buy an aftermarket "swap" crossmember, fab a new crossmember yourself, or modify the one you have now.

Those who choose an automatic transmission want transportation. Those who choose a manual transmission want to drive.

Well depending on WHICH turbo 350 your using (which tailshaft length) you can use the PG crossmember. The crossmember gets installed in the lower holes for the auto trans. The cross member also is slanted and for the life of me I cannot remember which way the slant goes at the moment. My gut feeling says it goes to the rear of the car. I am sure someone will correct me if I am wrong.

Yes, a TH350 with a 6" tail shaft will mount on the original crossmember.
When I got my Delray, it has a 350/TH350 combination and was mounted on the original crossmember. The short tail shaft helps with the front half of the driveshaft. Less to shorten.

ragtp66,
I believe you are correct that the slant go towards the back. helps with leveling the engine.

I'll be Frank, this hobby isn't getting any easier.
