early 70 series seat rails

[Heath]

Anyone out there with an early 70 series cruiser able to run a tape measure over their seat rails? Have a line on some old front seats want to check measurements first


I'm after the measurements for the rail mounts under the seat (where the rails attach to the seat, not rails to body). Width of front mounting holes and distance from front mounting holes to rear holes. Trying to figure out if 70 series seats will fit a 45 series if I use the 45 series rails.

Cheers in advance.
