I owned an '84 Dippy. To clarify, the frames on these cars were not necessarily weak. The police package M-bodies had issues with cracking in an area inward of the UCA's (if memory serves), but the civilian version did not. This can be corrected by adding reinforcements, and it wouldn't take much. Long before poly kits were available for this kind of Mopar, I converted the front end using hand-made bushings. That thing handled like a dialed-in roller coaster. It was unbelievable. I never had problems aligning it, and holy crap....did I ever hook turns in that thing. Lots of spirited driving being that wheel. It was so much fun, I couldn't help myself. It remains one of the best handling cars of that size that I have ever been in. My only complaint is that the 7-1/4 it came with was TRASH. The brakes were plenty big back there, but the rear itself just couldn't hold together. I put 100K miles on that car by myself, and the rear was apart 3 times. If it had an 8-1/4 and less rust, I would still have it today.
