It appears that 1970 seats had the seat back flip down lever in the middle / side of the seat and mine are near the base of the seat back.
I've looked at '69 high back seats and the lever appears to be like mine, near the base....
Also, I've not been able to find any covers that are like mine, i.e. smooth vinyl. They all seem to be more like the comfort weave vinyl.
If I knew that a new set of '69 covers will work on my (good shape) cushions, I'd just order them and hope for the best.
But it'd be nice to know what exactly I have...
Thanks!
