I've got '69 standard seats with headrest in my '66 daily driver, but they are starting to rip. My back seat is ripped too. I would like to have the interior match front and rear as close as possible. Will '66 seat covers fit over the '69 seat frames that I have, or is the '69 seat larger. The headrests are in OK condition, so this isn't an issue. I'm sure it's not a perfect fit, but I am wondering how much fudge factor would be involved. I guess the other option is to find a custom upholstery shop, but I would prefer going the less expensive route and putting the cash to more important upgrades. Any ideas?
