Sorry, I'm horrible about keeping this stuff updated
Got the guts from the prostreet trans cleaned up and re-lubed, and assembled into my '67 case with all new gaskets and input shaft seal. Has heavy duty 3rd and 4th gears, super diff and I installed a beefed up throw out bearing arm. None of it was as much of a chore as I was afraid it would be. I painted everything before installing the diff so I would get paint on the purdy aluminum side plates.
I haven't taken any more pictures yet, but I've since installed a set of short axles (to replace the '67 long axles), seam sealed the chassis where I welded in the new pans and painted a few of the removeables (spring plates, trans mount, etc). Still have to cleanup, paint and install the axle tubes before I start re-assembly of the chassis and putting all of my new parts to use.
Hopefully I'll have many more pics to share soon.
