Seat foam for "S" type

Hello Folks,
I am having trouble sourcing replacement foam for my “S” type seats. Anyone have any leads? I am on the NE coast.
Thanks

A number of years ago I got replacement foam and leather seat covers for my S Type from Aldridge Trimming in Wolverhampton. They made up the black seat covers in a few days while I was on a UK trip and I lugged them back as baggage. So far I have only fitted one section, the bottom of the driver’s seat, the originals are still passable albeit with some patina in 54 years.

I had my local upohlstery shop just make up the foam from bulk generic stock. It worked fine. There did not seem to be any real magic to the chore.
Do soak the hell out of your leather with neat’s foot oil for weeks before you start to take the seats apart. You will have to pull the hog rings off the bottom of the frame and your leather is now getting brittle. You could destroy the covers taking them off.
