With the heads ground off the rivets should be able to drill into the them enough to clear the control arm.
Thanks, I was a little hesitant to drill them out, but that certainly seems like the best option if I choose to keep the original suspension unit.
Get rid of the torsion bar front and install a 63 and up suspension. Swap the whole front suspension as a unit for a whole donor unit. Other wise parts are hard to find.
ClickThis was also suggested to me by a couple of buddies. I guess that would probably be the best way to do this. Thanks for the forum link, that gives me a good idea of how to plan everything out. I'll have to go check out some wrecking yards and see what they have. Thanks for the advice!
