Post up in classifieds, you'll find an 86 350X swinger from 25-60$. \
Are you sure it's an 87 200X? There red in color but paint can change....
New seals in thew front and fresh oil and your good.
Contact SBLT on the board for a rebuild shock, roughly 200$. Or gamble with a better used one on EBAY. Search "shock rebuilding or rebuilt shocks etc etc"
Neither the 200X or 350X have linkage, that swinger could probably be made to work, but something got rigged on it so it's probably 2"s lower or so.
The 250R swinger needs uses a linkage suspension and ears would need to be welded to the 350X frame to work. It would be great, but quite a bit of work unless you do that sort of stuff.
