Rear Seat Conundrum

You built quite a nice Duster. Love that red.
I have a while back got the measurements for the two lower seat hooks on the floor for a member here. Should be a piece of cake for you to replace them. If you put a wanted add or find them new,
I'll get the measurements from my 70 Duster floor for you. (I don't know if there's any difference from 70 to 74)
