Upper Control Arms need changing?

[kittypancake]

I want to improve my brakes, but I'm limited in skills, $$$, and would like to keep my 5 x4 bolt pattern. To replace my 9" drums w/ 10" drums on my '72 Valiant do the upper control arms and/or ball joints need to be replaced? For that matter, the lower ones too. I've asked a couple people and have gotten different answers.

Nope. Upper control arms are the same and so are the lower ball joints.

Upper ball joint the same too?

Upper ball joint the same too?

yes. the same.

There are differences in the spindle to lower ball joint bolt locations but I cant recall where.
Easiest way to be certain.. Go to a parts look up and get a part number for 6 cyl. build 9 inch drum lower ball joint. Then get a part number for V8 10 inch drum lower ball joint.

Keep in mind that changing from 9 inch to 10 inch dum brakes isn't going to make a huge difference.

Yes on above. There is only one part application for the lower ball joint for drum brakes for a 1972 abody. 9" and 10" take the same ball joints.

this swap made my 62 valiant stop much better than, the 9" brakes-- An early 70's duster (i sold) with power 9" brakes stopped better than the 62 valiant --in either form of brakes.

just my $.02
