67 vs. 69 bucket seat question

[jg95z28]

I'm thinking of replacing the aftermarket highback seats the previous owner put in my 67 coupe. It originally came with deluxe bucket seats with headrests (which are now long gone.) I know even if I can find a pair unrestored, they'll still cost me a fortune. Since I'm not going for originality, I was wondering if replacement 67 deluxe seat covers would fit a 69 seat. I'm guessing I might have to swap the std. 69 seat-foam for repo 67 deluxe foam, but otherwise would this work?

BTW - I don't want to simply use 69 upholstery in front as my backseat has already been recovered and its done in the 67 deluxe pattern.
