151 track from a 144

[ArcticDoo2]

I have a 2001 Summit 144. I want to make it into a 151. Just wondering if I have to do a skid setback or not. I have been told both ways and just want to get some opinions on that. Can i keep the stock tunnel the way it is too or do i have to extend it? Also, what track has people had the best luck with and will a 16" wide fit under the stock tunnel.
Thanks

From what I have read on here, you can keep the 144 rails, do the skid setback and the guys that have done it say it works great. I have not done this. Mine came from the factory with the 151. I have been told to do the setback to get the better track angle that the 02-03's have. Maybe next year.
