Post subject:  Disk/power breaks

Hi, I have a 1970 Dart 4 door and it dosen't have power or disk breaks. I was wondering if I could use a similar car for these components from the local salvage yards?

Yes. Better yet, use parts from later ('73 to '76) A-bodies, and rebuild/upgrade your suspension in the process.

Do searches here and elsewhere on the web.

mopar disk brake swap, etc

thanks! Would suspension and brake parts from those years bolt up with little or no fabrication?

actually, you don't really need the LCAs as the lower ball joints have the same size/taper stud. just the UCAs and everything in between. i think the later, big bolt disc setups used a larger diameter strut rod. so if you decide to use the later LCAs, be sure to get the strut rods as well. as a bonus you'll get a minor performance upgrade via the stiffer rods.

The strut rods connect to the LCA's and K-member, so the originals can stay (assuming they're straight).

I believe this photo was taken before I mounted the calipers (80 Volare, to the rear).
I'm using the original strut rods and LCA's (with homemade plates) with the 73-76 A big bolt pattern disk knuckles, balljoints, UCA's, rotors, master cylinder, and C-body tie rods.
