81R Problem HELP forTF

[200xman]

I put a Durablue +4 in my 81 with the 300 kit that I bought off Ebay. The sprocket is not held to the axle with a snap ring and washer like stock and only relies on the 4 rubber bushings. I took it for a quick blsat down the block and blew the sprocket off the bushings halfway through 5th. Does anybody make a solid rear sprocket for the 81? I'll be very unhappy if it can't make TF.
