John, the 03's were a little weak around the front shock mounts on the frame... none of the Z's had a round carrier stock, so it is an aftermarket if it's round. Good thing is there are soooooooooo many parts out there for the Z's. I had an 05 and loved it. Never had a problem. I love my 09. Great buy and another project to keep you and Landon busy. Buy it!!
