Parts sourcing question

[Steven R]

I have a 1971 GMC 3/4 ton LONGHORN 2WD

I cant seem to find a place that sells the U bolts to fit my truck, It has the aux overload leaf and spacer blocks in it from factory. Do you know of a place that sells them, and have you seen them or installed a pair from your source?


every thing i find only asks for 4 or 5 leaf but nothing with an aux overload leaf added like the pics. Or what should I be looking for or be calling what I have.

Hoping to match factory as close as possible. My plans are to have it sand blasted and painted but before I cut the bolts I want to order new ones. I have been trying for a while now and they won't move.
