Does anyone know the relaxed length of the rear coil springs on a 2005 dodge magnum rt RWD? The parts are discontinued through Mopar and now need to be bought by third parties. I tried an Autozone part and it was difficult to install. The Autozone length is 14.7 inches but compared to the original it is longer. I found a 13.5 inch spring by Mopar on EBay it it’s not for my VIN. I’d appreciate if someone can help me out. TIA
