I will get out this morning and take a picture of what you need to adjust. about 5 minutes work... mine has been off for about 5 years, just never seem to get around to adjusting it. Thankfully one has nothing to do with the other... (steering wheel being straight and the alignment).
Also anyone can align a D1 or D2 at home just remember it is set to zero... measure the distance between both front tires (front of tire, and back of front tire... they should be the same distance across.)
