Hey thanks! I was reading an article and it said that the pin was no longer( or hard to get) available for this swap?
Here's the article

Whats the size  ( ID)of the  73-74 spindles? I just pulled off my rotors and measured. The inner bearing ID is 1.375" and the outer is .750" I'm trying to figure if I have 70-72 disc brake set up (I have a 70 Challenger, originally with a 6 cyl, which should of had drum brakes I'm guessing?) or a  73-74 set up?
Thanks guys!

1.375 is the later 73 and up spindle.

I just bought 4 pins when I redid my brakes a few months ago, got them at Kragen. They had to be ordered, but they showed up in a day from the local warehouse...

Perfect! I love it when things go right! Now I just need to get new rotors to compleate the big brake conversion! I just bought the caliper brackets off E-bay! Anyone know of slotted/drilled rotors for this swap? Do they have to be for a cop car or will regular 76-78 B-body and 79-81 R-body car rotors work?
Thanks for your help!

There are plenty of drilled/slotted combo's on ebay, although I'm not sure about their quality. They don't have to be cop car rotors, any of the late 70's 11.75 disks should work. They also came on the big cars, cordoba's, fury's, new yorkers, etc after 1975. This is an application guide for the 11.75 inch rotors off of RockAuto...

Thanks again, but I went to O'Reilly Auto Parts looked up front rotor for a 79 cordoba and got wagner part # BD60474   then looked up a 77 Fury and got wagner part # BD60472 ?? Any idea why the difference?

[72bluNblu]

I'm not entirely sure, but some of those cars had 11.75" brakes as an option and had 10.9" brakes standard, so it lists both the 10.9" rotors and the 11.75" rotors. The parts guy might have just given you the first one that popped up. The cars with the 11.75" brakes in the front also came with 11x2.5" drums in the rear.

Wagner BD60474 the one you want.

used NAPA's parts pro to cross reference. Rotor thickness seems to be the dif.
