Differential U bolts?
Well took the truck out today.. And noticed a incredible amount of rattling when driving on the un-paved road... Got it home and put it up.. While checking everything I noticed that the u bolts were bottomed out.. But still loose by about a 1/8"... ( so when up in the air the differential was basically hanging)
The previous owner changed them.. There way to long.. Can anyone tell me what the correct length would be...from what I measured I'm thinking 9".. also having a hard time finding the correct square bend with a 3" center to center...
Any help in locating the correct ubolts would be appreciated..
Thank you

Not sure where you live, but a town of any size probably has somebody who can make them while you wait. Maybe ten bucks a piece. Measure what you need. It's important to specify whether they are half-round or square, they look similar. If they are loose the springs in the pack will probably break.

I don't think I have a spring shop around here....(had quite a few in Boston).. Hoping for something off the shelf...I'm pretty sure I need the square.. But wondering how to measure the bend..ID or OD or center to center?..

To determine the correct u-bolt length, the number of leaf springs must be known. 1965 F100 2WD's could have 5 or 6 or 9 leaf spring packs.

Any speed shop with an online presence ought to be able to make up what you need.
Look for ones that do replacement springs - they make them up all the time.
When I replaced the rear leaf springs in my truck, I got the complete setup for about $500 but that was back in 2011. I'll type up the company information, and the specs from the invoice. It includes the measurements for the U-bolts, which were for the new springs and the Ford 9" rear axle.
If you have a Ford 9" rear, then these measurements will be close. The company you deal with should ask the right questions about your existing setup.
Here it is, and Best of luck!
