Generally, the front doors on a two door car are wider than the doors on a four door car...........they narrow the doors on the four door version to squeeze two more doors behind the front ones. So to convert to a two door there are two ways to do it. First is to find two front doors from a two door, graft those in, and modify the area behind them to fill in what hole is left from the rear doors being there at one time. The second way is to stretch the existing front doors by adding metal to them to make them wider.

We got involved with doing the four door to two door conversion on a 49 Ford we were playing around with at one time. (We ultimately gave up because we decided this particular car wasn't good enough to spend more time and money on) We did the route of buying two front doors from a two door and gutting the area where the four doors once sat. Then we were going to cut up the two back doors and use the sheet metal to fill in the voids.

If you just weld up the back two doors and use the old front doors unmodified, it sort of gives a funny look to most cars as the fronts look too narrow and the back area ends up looking too long. As was mentioned, it can be done, but is a lot of work to pull off correctly. I also agree that the four door versions of that particular car are pretty cool as they are.

Here are some shots of the 49 we were hacking up and what it looked like once the front doors were swapped out for two door versions. The 3rd picture shows the difference in width between the old doors and the new tudor doors.
