Hello Everyone,

New to the forum, research and reading via google led me here. I am looking for answers regarding driveshaft. 5.3/4l60e combo from my 2003 suburban which will be getting an ls2/80e combo but another story. I bought the Tejas Steel dual exhaust crossmember and motor plates(older not revised version). Will I need to do anything to the driveshaft, the motor mounts will allow motor to shift 1" to the front, i believe to clear the ac compressor.

Thanks
