My 80012 calipers came off the brackets and the 86166 calipers won't go back on. Someone else here suggested that I modify them (grind them) to fit.The 1970 only and 1971 onward calipers "should" all fit.
Here is a picture of the 1970 only "wide mouth" caliper on a 1970 'cuda (casting #KH80012) followed by a 1971+ caliper picture of the "narrow mouth" (casting #KH86166).
There are a variety of lengths of caliper pins too- both for overall length and the unthreaded bolt end.
Brake Warehouse outside of Minneapolis can rebuild the calipers- talk to Brad, he's "the guy" for master cylinder work too.

Yes I know just showing some differences.Challenger RTA, that's an interesting article, but I already have disc brakes. I just need to figure out how to make them work.
OK cool. Are any of those for sale? Do you have the brackets I need?Yes I know just showing some differences.

Sorry no. check the casting numbers against yours. Car was built 11-70.OK cool. Are any of those for sale? Do you have the brackets I need?
OK I appreciate it. I may have to go that route if I can't find the different brackets.If you still haven’t solved this I had my original ones rebuilt by Brake and Equipment Warehouse in Minneapolis. They’ve done three sets for me on 3 different cars. Might save you some headaches.
I had the same problem with Calipers on my 72 after sitting for 30 years. I adapted a grease nipple to the bleeder port and used a grease gun to pump them out. A little messy to clean up but worked perfectly.The car only has 66,000 miles on it. I'm pretty sure they are OEM.
I have a 20 ton press. I'll get them apart one way or another! 😊 I've got them soaking in pb blaster now.I had the same problem with Calipers on my 72 after sitting for 30 years.
