Hyper 9e and Tekin T8 question

[lambchops]

My old man has built his Hyper9e but says hes having trouble getting the motor to line up on the motor mount with the spur gear. Ive not seen it yet but hes talking about having to dremel something and only being able to get 1 screw in to the motor.

Has anyone else had issue with this motor car combo fitment, it could be hes doing something wrong as im sure it will fit!

Thanks
