Hello. New to Big bolts & this group. Got a 1967 Chevy C-50 dump truck a couple of weeks ago. Drove her 100 miles to my location. Next day was sett'in to trouble shoot rear brakes & found that both U-bolts on driver side rear axle were snapped (one towards front/ other towards back). Actually one of the broken U-bolt is really a broken ear on the botom axle plate. Just barely made it back here that day. Ain't drive'in her `till that's fixed of course. After lots of cleaning the bottom of the plate, I think it reads #3765663. The truck has a 2 over 4, w/ air lines running into the pumpkin. The pumpkin housing has no bolts in the back. There's 12 hex bolts on the drive shaft side. Can anyone tell me what make/model (etc) the rear axle is? Thank you.
