Kelly,
The "dynafocal" type mount has been tried on t= he rotary but has not worked out well..One of the obvious rotary traits is t= hat it has a hot and cold side. Various methods have been used to limit this= but there is no way to eliminate it completely. Because of this the engine t= ends to "work" and move around on the studs. Using the engine as a stressed m= ember is not recommended with the rotary. If  you were to do this anywa= y I wouldn't do it without a stud kit. You will have better results usi= ng a bed mount. YMMV
