I know that I put this in another forum but I didn't get any help yet. I have a 93' arctic cat 580Z and I am putting an ETT suspension in it. When I got the suspension they did not have the sled so I couldn't take measurements. 1997 was the first year of the ETT skid. Could one of you with an ext or zr, 97' or after, take the distance from the drive shaft to the front hole and then from the front hole to the back hole (center to center). Any help would be greatly appreciated.
