Baja RPM Front A Arms Problem!!
 

I am building an HPI Baja from complete scratch. Yeah, It may come out to be more expensive but it's called a "hobby" and I enjoy building these. Anyway, I purchased the RPM front a arms and am running into an issue which I hope somebody can help me out with.

When I insert the supplied spacer, then the outter grey rod, and put the screw through the a arm, the screw seems to be too big and not wanting to fit through the spacer. Do I have to drill this bigger in order to fit?
