9" rear in a jailbar truck

[GB SISSON]

No old time picnic basket when the grandkids ride out to the lake with gramps. It's more like hit the convience store for a family size bag of cheetos and a six pack of coke and see if they can make it all disappear before we meet up with the parents at Cascade Lake.

I have been trying to have all the needed parts lined up and correct before I switch out the axles, so as to eliminate downtime. I think the springs are ready to go. I removed the original Ubolts, wire wheeled the threads sprayed them and reinstalled for time being. I have measured everything I can think of and now it's u-joint time. It sure seems that the old driveshaft that was originally in the woodie before the T5 swap fits nicely in the yoke that's on the Lanny Pumpkin from Minnesota. Then I noticed the bolt holes for the ujoint's ubolts seemed further apart. This might be a 1310 ujoint with the 'big cap'? I read that was common on ford f100s. Like maybe one cross on the Ujoint has 1/8" caps and the other cross has 1/16th" caps. Both yokes have the same length for the distance between caps which I recall was 3.19". Confused? I am. In review: Both yokes on the '47 axle and the '71 axle are the same width, but the '47 centers for it it's 5/16" ubolts are 1 3/8" on center and the '47's are 1 5/8 on center, like it needs a larger cap.... Any body know these parts?
