This is a 1968 Belvedere wagon , it has 15 wheels , no sway bar , stock parts are better , thanks
If it was me I'd put the '73+ knuckles on there with 11.75 factory rotors and front hung calipers. Classic Mopar Action disc swap. Find the parts used or buy reproductions from DoctorDiff.
this is exactly what i did on my 67 coronet.
already had the FMJ spindles, you can order new spindles from Doctor Diff.
got the 11.75" rotors and adapters from Doctor Diff.
Also used his stainless brake hoses for front mounting the calipers because i think the brake hose routing is cleaner this way.
calipers were just remans for a 76 dart which should be a 2.75" piston.
