...   Jury is still out on my rear body mount.  In the pictures you can see how I cut and sleeved the mount that came with the kit and which extended to the very back of the body.  As provided by Kitman there was no way to install it after the body was on the chassis.  It may have been possible to install the mount first and then somehow slide the body over it, but I didn’t have enough willing friends to try that.  Then, I discovered that the exhaust headers on the front of the  engine (relative to the car) were obstructed by the mount.  Back to the drawing board!  The pictures show what I came up with - while not super proud of my welding skills, but I am good with a grinder!.  No matter what, this seems like a lot of weight and leverage on the trans mounting bolts.  I think CMC had a portion of the main (welded) frame extend toward the rear of the car which seems like a far better solution.

I welcome feedback.

I do not think the rear mount, that apparently is bolted on by the trans bolts, is a good idea.  That is one helluva moment arm on the frame horns.  The frame horns were designed to support the engine and trans, but I would not want to add the extra load, especially extended out so far.  Actually, many folks (myself included) add a kafer brace to help support and stiffen the frame horns.  This is an indication that the horns are not a tremendously strong part of the frame.

I would attach a rear mount that is designed and attached more like the CMC frame.  It could be welded/bolted to the subframe on each side and form a u-shaped support frame around the rear of the engine compartment.
