Post subject:  disc brake options

as suggested my andy, i decided to start this thread and hope it helps those considering the swap.
i have swapped to discs on several early a-bodies and have used both late model stuff and the ssbc kit and have come to a few conclusions.
first, the ssbc kit is great! very complete with high quality parts that are accompanied by very detailed instructions. beautiful 4-piston calipers and the rotors are plated to resist rust and are available with the small bolt pattern. another plus is they adapt to existing (good) suspension parts, brake lines and come with a new master cylinder. all for about a grand and worth every penny. if you are driving an early drum brake car with a cherry suspension and 14" wheels, this is it.
second, if you don't have a lot of cash up front (but lots of time) and don't mind swapping rear axles (for matching bolt patterns,) then just go for the '73-up stuff. best way to go is just buy a $100 parts car. with patience and a bit of PB blaster you will be able to lift the entire system (lines and all) and adapt it to any '63-'76 a-body, but beware there will be worn parts (rotors/pads/mcyl/etc) to replace along the way. but that's ok, since you'll be able to save a bit of cash for these parts while you work on tearing things apart (AND cleaning, AND painting everything.) of course now would be a good time for those poly bushings and torsion bars (did you buy a v-8 parts car?) that you have been lusting after for so long. your old 13" sbp wheels won't fit anymore, but that's ok since you found a good set of 14" lbp steelies under your parts car that the wife hates. plus a bunch of little crap like nice hood bumpers and fuel sending unit that you need but the repro houses rape you for (year one.)
my 2 cents.

Post subject:  The junkyard mix-n-match

Don't forget that there are a few other junkyard options. For example, if you're willing to run 15" or larger wheels, the 11.75" rotors - along with their caliper brackets - bolt to the '73-'76 spindles. I have these on my Dart and they stop very well. And there's some talk of changing the suspension geometry with F-body or late '70s B-body spindles to get a better camber curve. It's amazing what parts you can bolt together that the factory presumably didn't plan on being on the same car.

I'll throw my two cents in:

For over-the-counter kits I would prefer the Master Power kit over the SSBC kit just due to the fact that the MP kit uses factory replacement parts rather than unique parts. Either will work but I just prefer to be able to buy replacement rotors with a factory part number for the car.

Go to www.moparaction.com and then the tech section for the best guide to the late model LBP upgrade. There is also a section there on doing the Wilwood caliper conversion onto the 11.75 rotors. That is the setup that Lou has on his car.

Next step up is the Viper caliper onto the 11.75 LBP wheel. Still fits under a 15 inch rim. Eberg at Mopar Action runs this setup on the Green Brick. There is some stuff on the www.moparaction.com webpage or check out my website at www.arengineering.com for more details.

Ultimate bolt on kit available is the stuff from Baer. Doesn't seem to be too popular, and I haven't seen it myself in person, but it should work great.

Custom stuff is also available. I've built several custom setups including the Viper based 13 x 1.250 rotor and caliper setup on my '65 Coronet.
