Seat Track question

[1969 Project]

I just talked to my buddy who did the upholstery and he said that he noticed the seat tracks were different (not sure why he didn't tell me that in the first place) so it appears I need a 67-68 seat bracket and I can't seem to find anywhere that sells them. All I can say is the PO has definitely made this project an adventure for me. I am trying to get it ready for paint and it seems everything I touch is not as simple as it should be. and i don't even smoke.
