made my own, nothing even close to as fancy as everyone elses, i went from a 144 to a 151, i will post pics when i get it looking anything like a sled.... haha.
made my own here. its a 136 to a 151. this sled used to be an MXZ. i turned it into a summit. it turns out its hard to find a tunnel extension that fits a 136 MXZ to 151 haha
