Blas,
I did not take any photos of the transmission bracket beforehand, but am including a few more here. Each install will have to be custom made due to the particulars of the tail housing. Mine was off of a Galaxie, so I had to add a plate to the top of the poly mount, which was for a Mustang as the mounting points on the Galaxie are wider than on a Mustang tail housing.
Due to the size of the poly support, I had to fashion a deeper bracket than others have had to use as well. I used two 3/8" steel plates and a piece of 2" angle iron then had them wedded together. Bolt holes were drilled into the top plate where it attaches to the transmission mount cross member and I put slots in the bottom plate for making adjustments.
The existing driveshaft hoop looks pretty substantial to me, no plans on upgrading it. I did add a steel plate below it to lessen the chance of the driveshaft dropping to the track.
