I got under the hood to check my brake fluid and realized I was missing a cap on my steering shaft u-joint just below where it attaches to the steering column inside the firewall. The shaft is one solid piece with the u-joint at one end and the big "bell" shaped cup that fits over the end that attaches to steering box. It is a '75 F100 4x4 with Garrison power-assist steering. I have looked and I am confused on what parts I have. I would like to just find this small u-joint and replace it alone but haven't had much luck finding one for sale. Does anybody have a part number or source for this part? Number Dummy??

 

Did some more research. Looks like I'm stuck ordering a Borgeson 000970 replacement shaft...? That sound right to everybody? Are all these trucks the same dimension and spline count on these parts?

Was able to cross-reference the Ford part# to 'Spicer 5-92x'.

Notice in the pic what 3815 looks like. It's not the part the OP circled in post #1 pic. What the OP circled is part of the 3B676 lower steering shaft & coupler assy.

 

Thanks Bill, I was wondering if there was a superseding number.
