Topic: 1969 Drive Shaft U Bolts

[Aussiemach]

Which U bolt would be considered assembly line correct for a 69 Mach1 with 351 windsor and fmx ? Build date of 26 Feb 69 at San Jose
Number 1 was on the car but no way of telling if they have been changed. Remnants of cadmium were on a couple of the nuts.

Have found them with the raised "dots" and without. May be two different suppliers or from two different machines that made them at the same supplier

I would choose either style but a matched pair

Great, thanks Jeff
