I finally got my parts today for my sled. I noticed the track looks a tad bit bigger. How can I measure it without cutting it in half and laying it flat? Also, the new/used track I got is missing 2 clips, can i just take 2 clips off my old track and put them on the new track? And how do i put clips on wihtout the tool? One last question, the rear shock has resistance one way but not the other, is that normal, or is there supposed to be resistance both ways?
