Sure look like 69 seats except the release on the seat back is higher on the 69 seats.
I was thinking 70/71 Torino GT seats.
My 70 Torino had the comfort weave similar if not exactly like the Mach 1. I am not sure about the latch location.
but that just the thing..i looked carefully at the bolts and they don't have any marks on them nor where they mount, i just never seen this style before..im waiting for the marti report from the person i bought it from and he says something about a sebring knit???
I agree with both Bob and Steven. The front seats definitely look very close to 69/70 Mach 1 with the stripe just below the head rest. But as Bob mentioned the release lever is much lower than that of the 69 Mach 1. I did locate a set of similar front seats online that appear to be the exact seats in a 70 Mach 1 seats with the release lever in the lower portion of the seat.

The rear fold down seats seem consistent with the 71/73 Mach 1. If you have or get a Marti report for this vehicle it will identify if you car came with the comfort weave seats and the fold down seats in the rear. This may help answer your question if these seats are original to your car or if they were swapped out at some point.
Those are 70 mach 1 front seats - someone changed them
Your door tag will be GA if it came with black Mach 1 sport seats
