Which t56 Crossmember?

Currently I am doing an LT1/T56 swap into my third gen. I was wondering which crossmember was recommended. I don't intend on buying one with a torque arm relocation kit unless you guys think that the 383 LT1 I am building requires it. The t56 came out of a 95 Camaro but the car did not originally come with that transmission so I am unsure of the year. My options are the Spohn crossmember which looks significantly thicker, or the unspecified corssmember listed here that seems to allow more space for exhaust systems. If you guys have any other options I am willing to hear them as well. Any and all help is appreciated, and personal experience would be awesome, thanks!

Re: Which t56 Crossmember?

I bought the hawks t56 longtube crossmember, I had the umi crossmember with my 700r4, It was build very well but way too beefy. I ended up using the stock one and shaving that down even farther.

Best of luck to ya.
