I needed a tailgate for my '37-39 Chevrolet bed. I ended up going with a group that got good reviews and had a better price than I could find elsewhere, Mack Products.
https://mack-products.com/I suggest that you call, as they are apparently pretty busy after Mar-K went out of business. When I called them, they were very helpful. I see statements online indicating that Mack Products has purchased the old Mar-k line although Mack Products has been making truck sheet metal for quite a while.
I am very pleased with the tailgate I purchased from them.
