I seem to remember hearing that regarding Ford/Chrysler rim compatibility. Bolt pattern is the same, but the bevel is different, which could lead to lug nuts coming loose if not matched to the wheel itself.

I recall bevel angle is different between makes. Lug nut taper should match the bevel in the wheel.

My adjusters are OK. I want to replace all 20 lug nuts. Mine are a mix of originals and who knows what. Where would you go for 10 LH & 10 RH?

If there is a stripped adjuster, then the eccentric cam is probably frozen. So I would opt for finding a center support in better condition.

Danny –

No gasket. But there are tiny rubber seals between the hex adjusters and the backing plate on the inside, in order to keep anything splashed onto the backing plates from entering the assembly.

Folks:

In mid assembly of stock 300 F front drum brakes. Is there a gasket between the backing plate and spindle? Where can I get a proper set of fresh lug nuts 5 with LH threads?
