‘71 340 Duster Front Drum to Disk with Factory 14” Rallye Wheels - Problems

Thanks for the information. Measuring to the outside lip is 4-1/8” exactly. I purchased the car from the original owner. The braodcast sheet came with the car. I could be wrong, but I believe the codes verify a rallye wheel option. At an outside chance, I guess the original wheels could have bee replaced with aftermarket wheels at some point.

The wheel stamping is 14x6.

Pics of original broadcast sheet and the wheel stamping below. Please comment.

I'm not an original rallye wheel expert by any means, but my understanding is that 14x5.5" was the widest factory SBP rallye wheel. So 14x6" would be aftermarket.

I believe that the W21 on the broadcast sheet would mean that the car did originally come with rallye wheels, but of course that doesn't mean the rallye wheels on it are original.

It's a 50+ year old car, lots happens in that time even with an original owner. Parts get replaced.

i'll throw another log on the fire: does that rotor look weird to anybody else? like the snout of it is way long? maybe there's a manufacturing defect and it was cast incorrectly and the face of the rotor is supposed to be 1/2" further out?

but a +1 to aftermarket wheels maybe playing a role, and another +1 to tolerance stack and giving the caliper brackets the ol' loosey-goosey and a shimmy shake before taking a soft wheel to them.

Rotor looks pretty normal to me, the angle of the picture maybe making things look a little weird. The braking surface obviously lines up with the caliper, so, that part's not off. And the spindle dictates the location of the bearings, so, yeah. The snout looks long, but so does the rotor "hat" section unless you compare it to the caliper.
