new from tx

hello all, new to the rxr scene mostly quads and rock crawlers but got kiddos a 08 800 1 1/2 yrs ago. As some things go they were crawling on the back and ripped the Schrader valve, didn’t notice till me and the neighbor got on next thing I know its on its side. Any help locating a roll cage for it would be awesome and also looking at the new 900-1000’s any advice?
