Just a quick update.
I sourced a dana 300 , and placed it on the rear of the spare drivetrain to take a quick look at it. In the clocking position in the picture, the case is nice and flat, however driveshaft clearance will be a little tight, rotating it down a set of holes, is not an option for the overall goal, so a clocking ring may be ordered next.
I'm almost done disassembling my parts jeep, remaining items include, roof, axles and springs, steering column, dash pad and a few tim parts. Most of the interior that was in this jeep has already been reinstalled in my good jeep with the exception of the head liner and overhead console.
