What would you do

Several years ago, somebody on here installed a new AMD full floor pan for a 67-76 A body into an Early A. If I remember right, the main problem areas were where the trans tunnel met the firewall pinch weld right at the top of the hump. He had to trim the width just a smidge, but it looked like it went pretty well. Maybe someone that is better at snooping the forum than I am can find the thread.
