stock ubolts on my z were 6 9/16 overall ordered
so nos one's and there 7 1/16 is this the right
lenth or which ones are right thanks in advance

I don't have any idea.
My Camaro is a 67, which came with T bolts, no U bolts. I have a 69, but it's a race car and non-stock parts.

Tony,
I just installed new U bolts on my rear 7/16" diameter (stock) and 7 1/4" height with the "tall nuts". I could have gotten away with 7" height (the length).

This was on a 69' 5 leaf spring set-up using both the rubber insulators on top & bottom of the springs.

Sounds like what you ordered should work fine. If they are a little long you can always cut them off.

Thanks Drew looks like somebody would make
replacements the right lenth

I figure it is kind of a generic sorta thing since all we need to do is use a chop saw or a sharp hacksaw to cut them down..

I guess I'm being to picky just don't like seeing
threads half way up the u-bolts
