125-200cc Rebuilding rear shock 06 wr250

So I am wondering if you guys know where I can source a rebuild kit for my rear shock as it's got a pretty bad seal leak that happened right after I got the bike from the amazing previous owner. I have searched and searched, but can't find any rebuild kits for the rear Sachs shock on this bike. I even went and ordered a used te450 rear shock in really good shape, but it doesn't quite fit right because the bottom mount is an inch or so shorter than the wr250's. Any help would be greatly appreciated! Thanks!

Husky part number 8000A5072, get it from your dealer.

any suspension builder should have it. also you might want to change out the piston for a bladder it seems to make the rear shock a bit smoother, plusher.
