bought strut conversion kit 550.00 Just need to install & bye bye check sss light.
See if after market hydraulic/gas shocks are available, disable rear level switch or the pump.
this is the sort of thing i've been thinking about. will these shocks provide enough support to load car and pull u-haul trailer? thanks for your help cadillacowner
