I am not sure...

But this is what I did with my 1987 Camaro before I built a Tube-Frame for the car.

As long as you have sub-frame connectors along the body seam/ pinch points... you can do the following.
I measured and cut a piece of tubing (same size and type as the sub-frame tubes/bars).
Installed this tube/ bar under the floor between the 2 sub-frame connectors.
This tube/ bar intersects each sub-frame connector at a 90-degree angle (perpendicular) and welded the tubing together.
I purchased a tubular adjustable torque-arm made for custom installations... and installed it.
When done this way; the transmission that is used is not a factor... you can even swap transmissions, it won't matter.
Below is a photo of a similar type of installation, with a torque arm mounted to tubing attached to the sub-frame connectors.




This is a far superior method of attaching the torque-arm, over attaching it to the tail-shaft housing.
Attaching to the transmission cross-member is better from a leverage stand-point...
But complicates things with fitment of the transmission, drive-shaft safety-loop, exhaust, and anything else.

The remote-mounted torque as shown above, simplifies fitment, transmission selection, and retains a good amount of the benefits of a torque-arm suspension.
Here are a few more photos of this style mounted torque-arm:









I believe that BMR and Global West still produce this type of torque-arm for 3rd-Gen F-Bodies and 4th-Gen also...
There are more companies that produce these as well... Moser produces them to install a Ford 9" in a 3rd-Gen.
Simply purchase a torque-arm for a weld-in tube-mount/ remote mount... and have fun!

Thanks for the post and pictures. That helps big time. As far as the trans mount did you make that?

I used to make one like that...

Similar trans. cross-members are on the market though (for a 3rd gen).
