The weight of the bellhousing and transmission required me to switch to using stock parts to mock everything up to proceed with building mounts...

I picked up several sheets of decent sized 1/8" steel at the scrapyard and started configuring elephant ear type mounts...

Ultimately I added a 1 piece mid mount bracket between the bellhousing and the block...

In the end the 1/8" steel mounts were used as patterns to create the 1/4" aluminum mounts in the last picture...

Best thing is is I can set it down in the car against the mounts and then just add the bolts as the brackets lay on top of the frame...
