Hello all! I have read all the info about the disc brake conversion info but I still have an issue I can't figure it out. I have a 71 Charger. I am using spindles from a late 72 Charger to which I added the larger 11.75 Cordoba rotors. No problem there. I Picked up the larger Cordoba caliber adapters however, they will not bolt up to the spindles. The original adapters that came with the 72 spindles I am using are the smaller ones that accept the smaller 10.95" rotors. I am stumped. Do I need different spindles? Help!

I believe it's the 73 and up spindles you need, not the 72's.

Are you sure you have Cordoba 11.75" caliper brackets? The bolt pattern is the same for all 1970 and newer B/E/F/M/J/R body disc knuckles

Cass,Yes. I took them off the Cordoba myself in the junk yard. That's what I can't figure out. The Cordoba adapters will not fit on the 72 spindles..

I swapped those parts many times.

What doesn't fit? Does the bolt pattern on the knuckle match the bolt pattern on the caliper bracket?

Can you post pictures of the parts?

The bolt pattern is different. The 'spread' for the holes on the slider adapters are greater than the spread on the holes on the spindle. I am a positive that nothing was altered on the Cordoba from the yard. Again, the Cordoba rotors fit fine.

Well then, the only thing that i can tell you is someone put "C" body brakes on that Cordoba.
Who knows what could have been done to an old car throught the years.
Your options are.
1. Find another car with the proper adapters.
2. I can sell you a pair of the taller sliders.
3. DrDiff can sell you a pair too.

Measure (& post) what you have for C to C on the bolt holes in those adapters
