JOE, so your interior is more of an ivory colour - must be very light and airy feeling inside, unusual for cars of that time. Totally understandable that you want to preserve these rare materials by keeping them covered. Maybe someday, when the car is up and running again, you could get a zipper sewn into one of the covers, so that you can show off the original upholstery.
As I said, I love those Chrysler sedans and that shade of green is a perfect contrast to all that lovely wood. Yup, you've got pretty much what I'd like to be my last old car.
I see you've got a big Traveller roof rack, too. Did T&C sedans ever get the fold-down rear seat back that Chrysler and DeSoto Travellers had, opening into the trunk?
