I know this is a long shot.....I'm about to weld the Shifter Porch to the floorpan of my '69. Although it's sort of obvious where it sits on the tunnel, there is a little wiggle room fore-aft. Does anyone thats done a resto or may have the carpet out of theirs have any pics or better yet, measurements of where it sits relative to the tunnel? I've attached pics to show what I'm looking for. Thanks and stay safe!
