i went to order a 3inch body lift from summingracing.com today for my 2000 1500 automatic dodge andthe one for a manual truck is 179 and the one for an automatic is 266, why is there such a big price difference between the manual and the automatic?? a noviist question here but could i get the manual one even tho my truck is automatic or is there different parts i would need.? lemme know
