I think you might be better off a) finding and contacting an original mfg who still has the tooling, or b) making some kind of adapter board by pulling the pins from a DB25 and soldering them onto a pcb. I wouldn't be shocked if you paid them and got the first parts and had a problem. Then they will point to your lack of tolerance or chamfer specs or somesuch and then want more money to modify the tool.
