This is the step-by-step process of  fitting Subaru seats in a Mustang

This is the bottom of a Subaru seat before it has been modified.  Notice the irregular mounting brackets.
This is the bottom of a Mustang seat and a pattern for the retro-fit.
drilled seat track seatstud
I removed the tracks from the seats and then drilled out the spot weld and the rivit that was holding each of the original mounting brackets to its track.
After drilling holes in the tracks to match the Mustang bolt pattern (front to back), I welded in some nuts and fitted them with a piece of grade 8 allthread.
bar refit seat
This bar was fabricated to move the tracks inward.  The outside holes match the original mounting points on the seats and the inside holes are the new mounting points for the tracks.  I also moved the track holes further back to gain extra leg room.
After painting the pieces, I attached the tracks to the mounting bars.  Then, by measuring diagonally from stud to stud, I matched the measurements to square it up.  I then installed the bracket on the seat and put it in my  car.
