No dont mount it rigid, has to be rubber mounted you could simply do it with a steel plate and some rubber bushes cut out of some thick rubber sheet and a hole punch or if you got to a rubber place you ca buy rubber washers. Yeah i looked and no drawing for the mounts. I will try and remember to look at a mount tomorrow and if i can see it wont take me too long to measure up i will do a quick drawing but i cant promise anything.
