Congratulations on your possible purchase. The comments on the wood are excellent. The worst area could be above the windshield. This is not good because the screws that hold the windshield in the car go into the header above and to replace this header requires moving some sheet metal. Putting on a new top is not easy but doable.
Also, get in and out of the car to verify that you fit in it! 28 and 29 cars have too little space to swing your feet between the seat and door jam. People must have been smaller back then. Make sure you are happy with the seats. They are small in comparison with modern cars. I won a Victoria and the folding seats are only OK. After a four hour drive my back is killing me. I remember getting my first Model A (April, 1964). It was exciting. I now have three. Good luck, Ed
