I just picked up my car from the upholstery shop and it ended up costing more than I expected. I had purchased the preformed foam from Thunderbird Headquarters a while back and the seat cover set from Larry's. The foam for the front seats was so oversized, the shop showed me where it wouldn't work, no matter how much they tried to stretch things. I had 2 options: 1. to try and return the foam and have the shop make new from scratch. 2. Contour the pre cast foam to make it fit.
My thoughts were that it was probably easier to contour the existing foam. The shop did this, however that cost me almost as much to reshape, as I paid for the foam in the first place.
From my experience, I would strongly recommend staying away from the very expensive foam from our TBird shops and have a good upholstery shop make your foam.
The rear seat foam wasn't nearly as bad as the front bucket seats.
This was just one more challenge to overcome.
