SuperQ

I am in need of a little help. I have a supermaxx, and I was wondering if anyone else is running a ws7 in theirs. IF so, I need some help. When I got the engine, it didn't have the little screw in the end of the rod. I thought oh well, I'll just put one in, but all the screws I tried to fit in make the engine too long to fit from the engine mounts to the trany case. It fits ok if I leave the little screw out at the end, but then there is nothing to hold my bearings in my clutchbell. Anyone have any suggestions on anything I can do (cheaply) ? I have a mugen aluminum 3 shoe clutch, with a 14 tooth bell. Any help would be greatly appreciated. Thanks
