Hey guys I am in process of having a 9" swapped in to replace the 8.8 in my Bronco, it is an '89. I am keeping the stock t-case for now it is a bw 1356 I believe. I really don't have the green after the swap and everything to go all out on drivelines. What do I need to use the driveline that was attached to the 9" that I pulled from the '78 bronco. I am pretty sure the yoke is going to need to be changed on the tcase, but to what?? Thanks.

when i swaped out the 8.8 to 9 inch on my bronco i just removed the flat flange from the u joint on the d shaft and the u joint mated up perfectly to the 9 inch yoke.

when I did mine, it 100% bolt in, from a 7X' ford into a 89' ford

I may be doing the same thing with my truck. I'm sick of the 8.8 giving me problems....

Cool thanks guys

I did the same on my 89 F150 - Mine was out of a 78 F150... Everything bolted up, except i turned my spring mounts to make up for the 4" lift. Other then that, it all bolted up. Same joints. (Mine doesnt have the flanges tho)

(Mine doesnt have the flanges tho)I think most if not all 9" had the yoke style. Just an FYI most rear axles from a fullsize ford are "bolt in's". Well physically anyway.
