What Year Seats are These?

[Too Slow '90]

I bought these a while back to install in my '60. I thought from all of the threads I read that these were a fairly easy retrofit but I don't think I grabbed the correct ones. No electrics in them. The tracks are 5"-6" longer than the factory bench and even with the track backed up all the way to the hump in the floor pan they still stick out way too far. I saw a few posts where spacers were used for the front where the floor pan drops but these just don't seem to fit.

I'm just wondering if I grabbed the wrong year. Thanks.
