There is two different wood sets for the 26-27. From what I have figured out is that the early '26 has wood around the quarter & rear windows. The new and unproved '26-'27 has metal around the quarter windows, and around the rear windows, no wood. I have both types. Both have a metal brace that goes to the floor I had bought a '27 Coupe for spare parts for my '27 Coupe. and they are completely different under the skin. Under the dash it's a big difference. I replaced my cowl with my other one, and it was a can of worms I opened up. Even the "A" pillars are different. One the "A" pilars hold the dash mounts, and the other, the cowl holds the dash mounts. The rain gutters for the trunk is beefer & stronger on the later one also, and the header plate is also completely different design.
Here's pictures of both.
