I bought a 04 rev 600 which has been extended to a 151". The 151" is in bad shape so I bought a really nice 144" off of a 07 800. The number on the track is 504152730, 144x16 with 2.25 lugs it has small holes drilled in it and is in like new shape. My question is will it fit or do I need to change my drivers? It is just a backup sled so not really wanting to drop big money into it.
