Question about seat bums

I talked to an upholsterer at a car show and he said in his experience, all the readily available seat foam was coming from the same source. Regardless who is selling it. They are molded to get the contours and I guess nobody wants to pay for their own tooling to be made. Another thing is that it seems most of the 60's Mopars use the same part number. A thru C bodies. Trimming is required to fit some models. If a Mustang part works, go for it.

I bought a complete kit from Legendary when they had a sale. Typically you can save 20% if you order from a show or wait for the sale. The buns were the last things I later bought because they seemed expensive. The foam just deteriorates from age and that's a fact.

My thinking is I'm not going to go to all the trouble of rebuilding/finishing the frames, buying the skins and underlayment, and then skimp out on the foam. I see cars all the time at shows where the old buns were obviously recovered and it shows.

And....my 64 is a convertible and the interior is exposed for everyone to see far more than a fixed roof car. I have everything I need and was going to do it myself but I just may haul it all to a pro and get a 100 point job.
