I got a call Friday from the shop that has my MH, Rocky Mtn Truck Repair in Great falls Mt that the lower control arms with ball joints they ordered came in and they were wrong.They were going to work on it this week. They supposedly found a supply house in Ca. that bought up OEM parts from Chevy. They told me that they ordered the parts based on my VIN. I also gave them the ball joint numbers for Moog K6174 for uppers and K6511 for lowers and McQuay-Norris FA997 for lower. They tell me that the Moog part numbers are wrong also, I need a RH lower control arm and an two lwer ball joints that will fit. If any of you have some incite as to what are the correct part numbers and where to find them it would be greatly appreciated. I am getting desperate they have had the MH for 2 mos and nothing has been done yet. I don't want to drive the MH from Mt back to Ct in the snow.
