rear suspension upgrade !

Any problems with the size of the bolt hole on the front shackles? Seems to be a lot of talk about the front bushings are set up for a 5/8 bushing and the cars are set up fro 1/2"etc... Are your springs the Mopar Performance brand? Summit racing? Thanks

funny you say that, the bolt hole in the front bushing is bigger than the factory bolt / hole in mount. Pissed me off when i started putting it back together. I torqued the bolts down REAL tight and so far no noises. Is there a better fix for this besides drilling the factory mount holes and changing bolt ? You would think they would mention this when ordering the parts ! They are Mopar Performance springs, ordered from my Dodge parts department. Mancini told me the shocks i have were on crazy backorder, but my parts guy said they were in stocking depo and i had them in 3 days, no shipping !!!!! Got both springs, both shocks and rear poly-shackle bushings for $320 total ... awesome !!!
