I'm planning to build my own driveshafts for the 84 SAS'd Bronco out of square tubing, and would like to hear any input from othersthat have done this mod. The stock F-350 shafts are either too long or too short, and don't have very much motion for the Bronco. i picked up two pieces of tubing, one is 2"x2"x1/4"thick seamless receiver hitch square tubing, the other is 1.5"x1.5"x1/4"thick seamless. I'll do awrite-up on the actual build once i get the time, but am still looking at options for end yokes. i don't like the short ds yokes on the F-350 shafts, so looking at using some longer ones from the local tractor supply. these are used for pto shafts on shredders and such. My big problem is figuring out what length to cut the tubing, so the ds doesn't bottom out or slip apart. i found thru fitment of the two pieces that at least 12" of the 1.5" tubing is needed inside the 2" tubing to get good engagement without much wobble. My rear ds needs to be about 28"-29" total length, while the front ds needs to be 35"-36" long. these are measured while the rig is at rest. JSM84
I found this good write-up on how to build one and how to measure for it :
