mc54-250b rims

[Fatasjerk]

Hi guys. Im having some major difficulty coming up with a rear rim for my 2012 Roketa mc54 250b. for those that dont know, its a 13", disc brake and is for the 24 splined shaft. I thought these were everywhere for a while, but it turns out that the 19 splined rims are everywhere, these, not so much. Roketa says theyre out of stock, several other places say theyre sold out. in fact, ive only found one place that has them in stock, and they sure are proud of em. I was wondering if anyone knows of anywhere to get a rear rim for this thing, or if anyone has a non-running one for parts. hell, id buy used just to replace the severely dented up rim i have now. (previous owner jumped a curb). thanks in advance for any assistance
