also, when you mount the main gear (I have some addendum info from the D9)
I will give you some info to allow for the correct gear angle. Darrells gear is
awsume, and work very well. you want to make sure they sit in the mounts
with the rear most part of your tire as close to the back of the wheel well opening
as possible.

this allows for the proper toe angle when the gear are extended. the mounts on the
A8 are cut out to allow for the Sierra (GO BLUE) gear.
