If it's T-section styrene, Raboesch does make 2mm x 2mm. It was sold in the US briefly. A hobby shop in Austin still has a display, but most of the stock is gone. I just stopped by there. They do have a 2mm x 2mm I-section. Maybe you could slice off a bit for a T. Either way, 2x2 is made, it just might take some searching. Could be easy on eBay from Europe.
There are other resin T roadster bodies out there. Perry's Resin lists one. There's also one with stock hood and grille. Check here for a thread about the need for a '26/'27 Tee roadster ("Tee" spelled out. Not just the letter). But yeah, I would also love to see a kit of that. In the other thread, my suggestion was for a T roadster body on the upcoming Model A chassis, with engine choices from Revell/Monogram Midget racers; a Ford V8-60 and/or Offenhauser 4-cylinder.
