I've been offered a pair of 10" drums with good ball joints attached. The hoses are there and in good condition. These drums came off of an optioned out '72 A-body. One question remains though: will these ball joints work on a '69 Valiant that currently has 9" drum brakes?

Note: the 10" drums are small bolt pattern, so yes, my 14" rims are not a problem.


Thanks

Yep, this is the setup you want.

I performed this swap two years ago. You will need to change out the upper control arms to the A body 73 and later size to accomodate the upper ball joint. The setup works great and is an improvement over the 9" drums.

66Dart, this doesn't match my experience or the parts books, which is that there is no difference in the upper control arms or upper ball joints for '62-'72 A-bodies. They are all the same, whether used with 9" drums, 10" drums or disc brakes. Same goes for lower control arms, though there were lower arms with and lower arms without mounting tabs for a front sway bar. Aside from that, they're all the same. Lower ball joints are not all the same. The groupings are:

*1962 through 1972 with 9" and 10" drum brakes used one lower balljoint (two, actually -- one left and one right).

*1965 through 1972 with disc brakes used a different left and right lower balljoint.

I wonder if you might have used '73 or later 10" drums, which do use different (larger) ball joints and different control arms.

I believe the '72 drum brakes will bolt directly onto the '69, ball joints and all.

A good quick online Mopar suspension parts reference is here.

Thanks Dan, yeah that had me confused there too. I mean, the parts are off of a '72 A-body and going onto a '69. It had nothing to do with a '73 at all! LOL

What do you think the value of these drums would be? The guy hasn't set a price yet, but I don't wanna be taken either.

The 72's will fit your 69. No need to change upper arm.
The ball joint change was not until '73 as others have said.
