Need early 1965 Mustang Coupe Chassis/Body alignment specifications.

Thanks The Greek and 65 Fix up!!! I do happen to have the service manual and all of the assembly books. They only go over chassis alignment and not the top part of the aprons that hold the fenders on. My chassis seems to be in good shape and when I placed the hood and fenders on to check for fitment they all align well but I was wondering if my 3/4" difference in cross measurements will come back to bite me in the @$$ later on. I plan on doing some serious welding soon and I just want to make sure.

Thanks for your help!
