Hearing a loud clunk or pop from the front suspension is troubling. Suggest taking it to a alignment shop for inspection before driving a lot. There are a number of things that could be at fault in the front, i.e. failed ball joint, seizing shock absorber, bad A-arm bushings, cracked A-arm, something loose like A-arm attachment bolts, failing steering shaft rubber flex joint, etc.
If everything was adjusted and working properly up front, the lower right front side wheel should have more negative camber (tire top tipped in) than the higher left front side. The Pinto's unequal length A-arm suspension should gain negative camber (more top tipping in) as it is compressed and lose negative camber (less top tipping in) as the front end is raised.
Just curious, do the doors close okay and are the gaps even?
