I talked to my Goodmark rep over the weekend. I spoke to him about the fender issue and the floor pan issue. He is going to contact Goodmark and inquire also. As I understand it, AMD is the result of two of the Goodmark guys branching off and starting their own company. They have new deck lids available that are supposed to be spot on, but are about $500. The deck lids sold by Goodmark are the same ones that have been going around for many years from various companies as I understand it. I looked at my 72 fender and found it was correct. I will double check it to make sure. He said he will send it back and obtain the correct one for me.
