but they're bolts, not studs and Cass said he "can't put tapered bearings" on those axles with the 1.75 brakes.
An email from Cass
I stock A-body 5 x 4.5" bolt pattern axles for re-drilled 5 x 4" bolt pattern brake drums, but they are only available with Green bearings. $298 pair, assembled. They are not listed on my website. If you are interested, I can Email you an invoice and payment link. Tapered roller wheel bearings are available for A-body 8.75" axles that use stock B/E body drum brakes, though. Cass
