I am curious if a set of 8" billet idler wheels on the axle that were on an 07 summit will work on my 06 m7. will the axle with wheels bolt right in?? and if the axles are the same will i need a special block or something to center the wheels.. right now the sled has the 2 stock wheels that come on the outside of the skid placed in the middle of the skid on an axle. also does this affect the size of track i need to have on there?? its a 153 so can i just loosen it up if i put bigger wheels on ?? not sure how that all works... any help i appreciate.
