I don't think that you have to go to that extreme. I was looking at my old hard drives, and it seems like all of the pins are put in the same. If I was you, I would try and get a hold of an old 2 or 3 GB hard drive, pull out one of the Molex pins with a pair of pliers and see if you cant put it in the other hard drive.
Also, if you have a little bit of electrical experience, you could rig it up for temporary use with a pair of wire cutters, soldiering iron, and a Torx driver.
