full RMS suspension swap!

I did the rear suspension because... If you had seen my rear suspension, you would've cried. I can't even blame it on the 6.1 hemi. I've gone through 2 sets of leafs in 10 years. There's this mountain road I live near with some wicked turns, and one rosses a defunct rail road. One time I hit it a bit rough, and heard, " Poot Ting !!! and checked the car later, and I saw nothing. After that every time I hit 65 mph there was a weird vibration, like when your crossing a wood bridge. The springs were missing most of the clamps, The shackle bolts had unbolted even with nylock nuts, and the rear hangers, welds broke. Got another set of springs and broke the passenger side pack. Being that I have no faith in springs any more, I replaced them. ( this is not the typical results most people experience. )
