Dodge Ram Van 2500 Rear Door Compatibility

I'm looking for a replacement rear LH door for a 1999 Ram Van 2500. The vehicle is in rough shape so I'm searching local salvage yards. I found a '93 Ram Van 350 with a good replacement and it looks like it would fit by eye-ball measurements. Can anyone tell me the range of compatible model years for the Van? Thanks.

I pretty sure 1998-2003 are all the same. Prior to 1998 was a different body design.

Thanks. I was hoping that the body style changes were more upfront rather than the rear. Didn't get much interest from the shop I called when they realized that they wouldn't be getting any work from the deal...I undertsand that but was hoping....I appreciate the response. Steve.
