I found 2 sources online. Yes I have a ruler but I thought someone may have already done the measurements and have some valuable input.

I need the dia., and length See the diagram below.

If I read the link from TX Firefighter correctly, they should be 20" long (total length) and 5/8" in dia. with a 3" tube diameter. So basically I've answered my own question. Does anyone agree with these measurements??

Thanks for all the input!!!

Re: U Bolts - What Size??

OK,

Here is what I came up with.

"A" is 3/4 NF
"B" is 3 1/2"
"C" is 7 1/2"

These measurements are from a '69 C-10, 2 wd, oem coil spring rear end.
