I have 2015 High lifter 2 seater XP1000. I have reviewed xp4 and 2 parts diagrams looking at how these are built. *Also I’m completely aware it would be way easier to buy a factory 4 seater, but I have several reasons I want to go this route*

Reasons in Missouri, once you make the frame custom… you can do special inspection with Missouri Hwy Patrol with a 551 form and title as dune buggy which then leads to street legal. We have no other way to be street legal.
2nd selling and buying another I would financially take a bath both times.

So, most stuff is buy parts and add to my 2seater, exceptions would be I extend my own wire harness and I will extend the frame sections the rest is simple. From my research.

I ran out of time to go into more details, but will ad back my parts list and thoughts at a later time.

Curious has anyone else stretched theirs.
