I'm ordering new seat foam from classic ind for my 67 A body
Like said their foam is great for deluxe seats! Standard fair not so much! If you want a standard set with little work look elsewhere.
It is firm and nice on the backside if you are willing to take the time to customize. I was lessed than impressed with the fit of the foam for a standard interior.
On the other hand the seat covers and door panels and the rest of the interior pieces were awsome!
