I have a '98 Indy Ultra, and this winter I ripped the track apart on it. So after looking over a lot of track profiles, and look mainly at the prices, I've settled on one. A Camoplast Challenger with 1" lugs, and after inspecting the inderneath of my sled, and getting a semi-measurement I'm not sure if it will fit. It comes stock with a 5/8" track so I'm not sure if it'll clear the tunnel and the heat exchange protectors. Any Help? Thanks.
