There are a number of Fordbarn people, including me, that have 28 and 29 special coupes. Congratulations on your excellent choice of vehicles to restore. It looks like it is in decent condition, unlike the rust bucket I started with. I hope the wood is in good condition in your car. I spent a lot of time replacing the cab wood in my 28 special coupe. It wasn't easy. Assuming you are replacing the top material, make sure you have plenty of help and do it in the hot sun so the puckers around the quarterwindows can be worked out. I had 2 helpers tugging on the material while I tacked it in place. I basted it the first time (tacks only half way installed) and then retacked the material as we removed more wrinkles until they were gone. We did the top outside when it was sunny and about 90 degrees. We kind of burned our fingers on the hot top material, but got virtually all the wrinkles and puckers out of the material. Sorry to be so long winded, but I thought my experience might aid you a little.
