I'm sure you probably already tried this, but maybe try a different combo of screw holes on the motor faceplate. I know my revtechs with the lightened or more airflow type plate, there is only one set of screws that mount and work. not sure if that is confusing or not?

looks like a revtech anyways? different holes lineup for the pinion to be closer or farther away to the spur..

your picture doesn't make sense? haha it looks like the screws and the pinion should be able to move into the spur?

Take the motor out, and take a picture of the hole/motor guard area where the motor would sit.

Yes it does, but you have to grind some of it as it rubs the rack. Its not bad.

Are any of you that switched to the one piece top shock caps interested in selling your metal top shock collar that goes around the top eyelet?

Thanks
Dave

Thanks.
you have the wrong rear hanger on the car . it should be the one with the angle that allows the motor the move all the way forward . i bet the one you have on the car is straight up no angle.

Damn, the downfalls of buying something with 2 race days on it...
For those wondering i'm not running the lightened end cap on my motor.
