I noticed your arm mounts appear to be relatively straight from front to back.
I also got the stampede transmission and got all the hardware.
My arm mounts have an angle to them and no matter which way I mount them I either have a lot of toe in or toe out.
I've tried flipping the arms themselves and swapping the mounts from one side to the other but nothing works.
Are there more than one type of mounts fastlane is producing?
Here are some pics
