GV "is" way too pricey. I already have two late AOD's and two '03-up Police 4R70W's, so that part is easy. It just occurred to me that AOD's must be pretty common in the '80-'86 camp, right? Easy to find trans mount? Another Junkyard post?

Towing will be passenger car and light truck under 7000 lbs easily, combined with trailer weight. Former E-250 with 3.31's yanked this stuff around like a boss, as they say. Van was weighed on certified scales many years ago at 4950 lbs, empty with one full tank of gas. Not sure what the F truck weighs, but I'm thinking a little bit lighter than that.

Other option is Super Wide toploader 4-speed. OD is .81, first is 3.29. Would have to find somebody with pedal-to-lower rod parts from 351. I have trans, bell, flywheel, fork, TO bearing, shifter. Probably the best combo without changing out the rear gears. Unsure of the hassle involved in changing pedals. Maybe not bad.
