I'm not sure as the mounts are different and in different locations. Some of the suppliers like Danchuk and CCI have a special trans side mount that attaches to the frame horns but it is primarily for late automatics when using the original front mounts and the tail shaft mount. It is for extra support. You might take a look at it. You could possibly take out the frame horns and install a crossmember. However, it would be a lot of fabrication to do for a stock application.
