[updated:LAST EDITED ON Jun-03-05 AT 12:45 PM (CST)]I want to buy a 68 c10, but I'm having trouble deciding whether or not to hunt for a 4x4. How good is the system? Is it difficult to maintain? Its very hard to find a 4x4 version. If I were to get a 2x4 and convert (I know, I know - "just get a 4x4!" But they're so hard to find), would I need a new frame? Were the 4x4 frames unique? Thanks for your help!
