I want to order matching rear wilwood disk brakes for me 73 mach 1 Q code. I came with front disk and rear drum. When looking to order is asks if it's a big or small bearing and bolt pattern. The rear axle is the factory 9" but the gears were changed to 3:89's. Anyone know what answers are to this? Thanks

It should have the small bearings, but before I ordered the brakes I would double check, you never know what the previous owner might have done.

Factory 71-73 8" & 9" housings used the "small Ford" bearing ends.
