73+ ball joints in my 69

[arkracing]

I have a 69 1/2ton with the usual drum brake/non-power front end. I know that i can bolt the whole crossmember from a 73+ into my chassis with very little modification (the two bolt holes that don't line up)

my question is will 73+ ball joints bolt/press into the 69 Upper and Lower Control or "A-Arms".

I have a 73+ front end but the upper ctrl arms are Rotted (as I live in New England) and the control arms look the same size (other than the bushings)

so the question is:
will 73+ ball joints bolt/press into my 69 control arms so that i can use the disc brake setup out of the 73+

(I know that i have to also use the steering components from the 73+ because they are different)

Any Info is appreciated
Thanks
Andy
