Some of you may remember my story about the 31 a pickup that I purchased twenty years ago, and still have. I went to look at the truck which needed full restoration. While looking it over, I mentioned to the seller that the bed was not model a and the full steel top seemed odd. He agreed and we set a price of $650 and I brought it home.
It wasn't until I bought the book, How to restore your model a pickup, that I realized what I had. A late 31 steel top with widebed. Engine code was for late May of that year which is about right because engines were stamped and not necessarily installed right away. I have one correct rear fender and I'm still looking for the other.
One more thing. You will not find the correct aftermarket subrails, if needed. You have to buy full length tudor rails and cut them down.
