A body with an A833 and a Gear Vendor installed

I'm not familiar with the GVod box but I've put long tailshaft 833 OD transmissions in a 1964 A body and a 1969 A body. I made a plate 3/8" thick that bolts to the rear shifter attachment bosses and welded threaded bosses where the A body transmission bosses would normally be. In the early A body I had to grind off the old shifter attachment bosses up near the main case and I modified the mount so it's about 3/8" lower to get it to fit in the crossmember. Don't remember having to make any mods on the later A body except the aforementioned homemade plate.
