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

I was in error on the caliper brackets. These were included in the kilt and used. I installed these months ago ands simply forgot.

Cass responded and said that these wheels are not factory, and that they have a different offset and taper. I am very surprised by this, but you guys are more knowledgeable than me, as this is my first Mopar after years of Chevy. That said, I trust they are indeed not factory.

I am now reluctently considering aftermarket 15x6, 4”BS, 5x4 BP wheels. My intention was to use the 14” Rallye’s. If I would have know that these wheels would not work with the kit and that I would need to go with 15”, I would have upgraded to a better option that Cass has available.

I do want to be clear about this….Cass has been an excellent source of information and great to deal with.

Here is his response:
Hi Jim,

With the exception of the rotor bolt pattern and register diameter, the brakes are reproductions of what '73-'76 A-bodies originally came with including cars optioned with 14" Rallye wheels.

If I remember correctly, I trial fit an OEM 5 x 4" bolt pattern Rallye wheel a couple years ago. Unfortunately, my order of 5 x 4" brake rotors is in transit and I don't have one in stock to confirm fitment.

Looks like you have aftermarket Rallye wheels, however. The inside profile of the rim is not the same as an OEM 5 x 4" bolt pattern Rallye. In addition, an OEM wheel also has 3 3/4" backspacing. What is the distance from the outside edge of the rim to the contact surface?
