I guess my thinking was the welding, which I'm not a welder so I do not know about it. Thinking was not burning through another piece of pipe by using a solid bar. and thats what we did we started the front and went down with the back. All the research I had done watching mainly RZR people cut there backs was they were having alot of gap and having to pull the bar out to match the back again. This scared me enough to not start it and then on another forum I seen the first P4 chop, and he detailed very good on what he cut and where and how much. I think his cuts were 6 front, 7 middle and 6 back. So this got me thinking not alot of difference if any in the P2 and P4, I do like some people when I am bored and retreat to the Man Cave and sat in the chair looking at it, the next thing I know a tape measure is out and a grinder and the roof is in the floor. LOL I really do think when you go to put yours back on your gonna see with just a small push from another person it will all slide right down and into place and no bending at all to be done. We put a ratchet on and I think 2 clicks the rear fell in and that was only needed on the driver's side.
