Suspension questions

nope tie rods are different for a 70 from a 69, the pin is larger in diameter and the taper is different as well. you will need to use 70 outer tie rods.

if you are indeed talking about the upper control arms then, yes, you can drill riverts and use a bolt in style ball joint, every mustanger that has ever had the ball joints replaced had to go through this at one time since all of the ball joints were riveted from teh factory.

if you're talking about the lower control arms, that's a different story, for the most part the lower ball joint is not servicable and requires a whole new control arm, sometimes you might get lucky and find an old school replacement ball joint and drill the old rivets out and bolt in the new ball joint but it's not the safest idea and probably why you can't really find that style anymore.

Yes but you don't want to dig into the arm. I asked the guy's at my alignment shop what they do and they said to put an X on the top of the rivit with a die grinder with a 3" cutting wheel before using the drift or air hammer. I tried it and the peices came right off.

I did this several years ago. Not only are there three rivets at the ball joint itself, but the bracket that the ball joint sits in (which is part of the replacement part) is spot welded to the arm itself 2 or 3 inches up the control arm. I thought we'd never get them off.

I will never do that again. Whole control arm is the way to go.
