I am doing a disc brake conversion on a 66 Coronet. The donor is a 76 Charger.
Will the spindles work without any problems?

They will work fine. If your Coronet has a sway bar,the links will probably hit the disc brake calipers. If that is the case, and the calipers are sliders instead of pin type, you can swap the spindles side to side and make the calipers rear hung to get them away from the sway bar. Also, if the brakes off the Charger are the ones with the 11.75 inch diameter rotors, you will have to run at least 15" wheels. Good luck

Thanks for the reponse. I think that I have the pin type. That means that I can't reverse the spindles? Does it also mean that I can't install a sway bar?

This will tell you everything you need to know I have a '66 Coronet as well. This link is from the Tech Archive

No you can reverse the spindles just make sure the bleeders are pointing UP.

BUT the disc spindle is 3/8" TALLER than the B body spindle , there could be a potential binding issue wit hthe upper ball joint but no one has ever actually had it happen , that has been reported anyway . Also make sure the rubber flex lines don't kink through out the travel of the steering from lock to lock.

The taller knuckles to almost triple the bumpsteer. "Cruiser" types guys don't seem to complain, but I'm really into handling / cornering / steering precision, so the correct knuckles are the way to go for me.

And be sure to heed that warning (above) if you reverse 'em. Really, the only safe way to route brake hoses is crossing the steering axis. IE: Relocate the frame bracket.

The MA disco tech article is full of great information. In addition to that, I filled up several chapters in my B-body book with brake swap information.

I have a friend doing a 66 B body as well. He is using the parts off of a 1974 Dart. He asked me a few questions I didn't have a answer to, maybe someone here will.

What master cylinder should he use, so it will work with the rear wheel cylinders that are on the car now. Or, is the Dart and a 66 drum brake car using the same wheel cylinder bore size.
Should he use the proportioning valve from the Dart, or just buy a adjustable one.

Don't mean to butt in on your thread, but maybe we can all learn something

I ran the Dart and the tall knuckles.The tall ones are on my 65 now.Been on for 7 years street/strip and no problems at all.In fact they are better than the Dart ones.I run 69-70 C body masters on all the conversions I do.Just get a disc/drum master.Rocky

Thanks for all of the good feed back.
It's my understanding that one of the reasons the the spindles are longer is that the later models have a rubber grommet between the frame and K member.
Has anyone tried adding the grommet that was used on the 72 and up or welding on a 3/8" spacer to make up the extra distance? Could this caues any other problems?

It's really not a concern. Check out this comparison of spindles:

http://www.bigblockdart.com/techpages/spindles.shtml

It's geared towards A-bodies but it does illustrate that the height difference isn't that big of a deal. All of the "DO NOT RUN THIS BECAUSE IT'S DIFFERENT" warnings have been more theoretical than applied.

the rubber bushing on the later suspension is bigger than 3/8" . adding it won't change anything .
