I have a 66 Valiant that i am putting a 318 in.. I figured that while i have the slant 6 out i would replace the bushings and torsion bars.. anyway i realized i have the contol arm and spindles from a 74 duster with disc brakes, will these bolt on my car with 9" drums?? the control arms look the same, is the ball joint a different size? I already have an 8 3/4 with 11x2 1/2 in the rear but i figured its better to have more brakes than not enough.

Use the 74 UCA/spindle which does have a larger ball joint. Use your oe LCA and get a lower ball joint for a 74 dart w discs.

what he said!

lower ball joint is the same for all 73-76 A bodies, drum or disc.
