Hmmm .... I wasn't able to cross FP-9023 either.
FD-9023 works ... NAPA NUP 9344 (Raybestos WC-9344), but that number isn't listed to fit any Fords with that size of brakes.
1976 Bronco with 11 x 2-1/4
NAPA 370192 LH
These wheel cylinders fit virtually ALL Ford full-size, midsize, E-F150's ... so I think we're on the right track. Just verify that bore size, and perhaps the fitting size/orientation. I'm thinking that it shoud be 7/16-24 thread, but the online catalogs don't give those specs.
I may be able to provide more details from the Illustrated Buyers Guide (paper catalog) when I get back to work on Tuesday.
Thanks for the endorsement, Centerline.
