You are talking a lot of money I would do a lot of shopping. You can do most of it your self with the kits, But I would take the seats to a pro and have them retied and padded right, Then install the kit covers for a factory look.
I didn't see anything tied in my '64 seats other than a wire runs vertical and goes in a little 'sleeve' so that you can hog ring it through the foam to the springs to pull the center of the "tuck and roll" down. Pretty simple seats if you just remember or take pics on how you took it apart. You could add up what the kit costs then go out and compare i to upholstery places or find out what it would cost on top of the cost of the kit to install it for you. I'd just do it myself but that's me.
i ended up ordering everything but a dash pad and top from new england muscle. they have an ebay store and the communication was great. last month i tried to order the interior from dearborn but they lady over the phone said that discount codes do not apply to complete kits since they are discounted already and it could take up to 3 months for it to arrive.
now to try and get the car painted before all the interior piece start showing up.
My upholstery guy is dropping my seats off tomorrow.
Took the driver side rear panels off to try and tighten the rear side window (loose/rattled).
Took everything I could off to try and get the window out with no sucess (got the window loose, but couldn't get it out), but when I repositioned the window and tightened everything up, the window tightened up and the rattle went away.
i received everything yesterday. the seat covers and door panels look awesome. i cant believe how soon i got the interior kit after ordering it.
i would recommend talking to Becky from New England Muscle.
