Actaully, if he is using the 1-4635HD as stated in the quote above he is has a 1310 with one set of large caps and one small. U-joint, 1310 w/1.125 cups one end and 1.062 other side = 1-4635HD or 5-1201X

Yep, that is what he has, I found the PN in a ujoint catalog I keep handy. As far as torque, I am just a backwoods dude, I hang on the wrench until it feels tight

1350 is not going to fit in the 8" rear yoke. Its a big cap 1310.
It was good learning for me doing the research since I know GM rears but not fords, pretty smart idea running larger caps on the yoke.

I learned a lot when I replaced the 9" in my 52. It uses the Ford big cap u-joints, was the first time I had heard of them. Yes it is a good idea on Ford's part, I'm sure it helps when they get over torqued.

A big cap Ford 1310 is nothing more than a 1310 cross with two 1310 caps and two 1330 caps, the ID on both sets of caps is the same. And as such, the torque should be 14-17 ft/lbs per the chart. The 1350 is not a very common u-joint for the Ford unless is is something big, heavy or changed out.
As far as getting a torque wrench on the u-bolts-Good Luck. I agree with Dave just hang on it until it feels tight.
14-17 ft/lbs is not very much just past snug with some loctite and I would call it good.

mmmm... 1330 and 1310 both have 1 and 1/6" cap diameters, the difference between 1330 and 1310 is the width of the joint itself. 3.6 in vs 3.2 in
This ford big cap thing is not something I have ever heard of before, but I don't deal with old stuff much. Looked an awful lot like the 1330 x 1350 U-joint in my 88 mustang... learning all the time.
I have torqued my 1350 down to about 40 ft lbs... so far only several dozen 140 mph 1/4 mile passes without a failure. I'll keep you guys posted on cap distortion if I ever have to replace the U-joint.

1310 Big Cap for Ford. My calibrated wrist has tightened too many driveshafts to remember, still going strong after thousands of miles
Maybe Tyler will rejoin his thread when we are done hijacking it...maybe not!

Never mind my stupidity 
on my last post, I screwed the pooch on that one. It is a 3RL (1.125 od) style cap on either of those joints that make it a BC Ford.
Probably not on Tyler rejoining, he said I got my info, got it together and said I am out of here.

I thought it would be so simple! I am having to replace my drive shaft cuz its too short (see above) but I'm gonna wait until I have the rest of the truck together and the weight on the axle to figure out the right length. Then I'll be back into this one. Y'all sure know a lot of details about this stuff!

i didn't read all the post on this.. but the first post u did of the rear and said it's a '66 mustang.. i don't think so.. a '65 & '66 mustang rears have a drop in axle tube size.. the '67 up did not, they are the same size all across. so from your photo u have a '67 up.

I was also told that it might be from a galaxy. Is there any way to tell? T
