Does anyone have a Hawks LSx T56 double hump cross member laying around?

I'm looking to have a double hump T56 cross member modified with the Spohn torque arm mount and was going to purchase a new Hawks cross member if nobody here had one they wanted to sell. Just figured I'd check before I went and bought a brand new one.

I may have some parts to trade for it if you are looking for anything that I might have. Let me know.

Here is how I made mine to work with a full length arm:

It's totally off the trans tail shaft, and is rock solid. Just have to shave off some of the original poly mount to get enough clearance.

Judging by the flimsiness (I like to make up words) of that cross-member, it appears to be designed to only support the tail shaft of the transmission. Do you really think it is suitable for a torque arm mount in a powerful car?

Blue, I've got an old, but new, Spohn torque arm and cross-member I never used that is set up for a Tremec TKO transmission. You might be better to modify my Spohn unit into a double hump than to do vice versa with the Hawks piece. Mine has adjustable pinion angle and spherical joint on the front with a slip yoke inside an accordion boot. You can see the cross-member is constructed of angle iron and steel plate so it is easy to modify and weld. I'm in Peoria, IL. PM me if you're interested. I'm going to be ordering a Jegster torque arm soon so the Spohn piece is coming off my car. It's basically been stored on my car for a decade instead of being inside the original box.

I have 100% confidence in it for what I do and don't do with the car. If i didn't have the TA for a track car, I would build something stronger for side steppin the clutch on the limiter with radials lol.
