21 RMAX2 and 25 RMAX4 compatible?

I got a 21 RMAX2 and thinking of moving to a 25 RMAX4, but I want to reuse some parts and avoid a complete rebuild.

Particularly, can I transfer the rear window, bed-mounted spare tire carrier, bed box (all factory), EMP front glass windshield, and the bed rack I made (if the 25 has the same size and structure as earlier RMAX2 models)?

I'm also concerned about fitting my current bash plate, plow mount, block-off plates and Super UTV steel protection plates. Anyone familiar with related dimensions here?

Basically, I need to confirm parts compatibility to check if it's a wise move.
 
The rear window, bed box and emp windshield should fit without much fuss. Custom items like your bed rack might need slight adjustments. The bash plate and plow mount could vary depending on frame updates.

some of the parts can be fit, like the factory bed accessories and the rear window. The windshield might. but your custom bed rack and undercarriage protection will likely need replacement or significant modification bcs of the longer RMAX4 chassis
 
Yep,totally makes sense. A lot of the bolt-on stuff like the bed accessories and rear window usually carry over, but once you get into chassis length changes like with the RMAX4, that's where it gets tricky. Custom bed racks, skids, and undercarriage parts often won't line up without some chopping and welding. Curious if the OP is thinking of fabbing new mounts for their rack or just starting fresh with an RMAX4-specific setup
