I have an 07 LTZ, my driver seat stopped sliding back and forth so I picked one up at a salvage yard, it slid back and forth but was stuck in the most elevated position. So I took it back and they had another, it went back and forth up and down but the lumbar did not work LOL. The guy at the salvage let me keep both seats to make one with everything working. So now I have essentially three seats and I need different components from each one to make a perfect seat. Does anyone know how to take off the whole backrest piece or if that's possible at all? Thanks in advance.
