So your say a 3/4 ton 88-98 ball joint will press into our old a-arms ?

And is needed for the 1/2 ton lift/lower spindle ??

I am checking on the lower A-Arm ...I have a pair of 3/4 lowers in storage and I will grab a pair of calipers and do some checking. I would hate to have to sell my brand new tubular lowers...

If the lower mounting cup is different then yes you would need 3/4 lower arms (I saw a bunch at the U-Pull It yard a couple of weeks ago)

The upper arms, the ball joint just bolts in, no problem there

I'm collecting parts for this conversion also.....yes you do need to use 3/4 ton lower a-arms (the '67-'72's have a lower bumpstop mount). I'm contemplating doing a little surgery on some '73-'87 1/2 ton lowers so I can use them since I like those bushings better. For more info on this swap HERE is the thread in the FAQ's. I can help with part numbers if anyone needs help finding the parts.
