Any hardware store should sell a good range of metric & imperial screws- take the motor along with you to check they fit. Just make sure when you mount the motor, the screws dont go in too deep and touch the windings- trim screws or use washers as needed.
thanks.i also have mod 1 pinions for my 9xl.but forgot what spur/clutch im supposed to use for my emaxx.what spur /clutch system do u use?btw its 3906
If you want to stay with mod1, use a monster gt spur - they are direct fit and are mod1. Tower says they are 32pitch but this is incorrect info, it is mod1.
just wondering, did you buy this motor new or used??
someone may have sold you a motor with stripped screw holes, if so are the other 2 screw holes stripped as well, you will have to retap some new threads in the end bell
