WCIGUY,
I will break this down for you, and others will also learn. If you know this already, then I apologize. But not everyone understands this stuff, and knowing a little bit about the codes in the book can help you find parts easier. The Door you want is listed in TM 9-6115-642-24P, on page, (PDF Reader page number) 24. Its listed in Figure figure #5, item number 24. I have printed out part of the listing from that page below.
You see the Item number then the SMR Code. What is the SMR Code? Its means Source Maintenance Recoverability code. Maintenance and recoverability are not important in this problem. But Source is. At the front of the manual is a listing of the Source code. The first two letters of the code are the Source code. If you turn back to the SMR code explanation you will see listed next to XD, Item is not stocked. Order an "XD"-coded item through normal supply channels using the CAGEC and part number given, if no NSN is available.
That means, the military did not stock this item. You could order it, but the chances of getting one were slim. Normally, CECOM would wait until they had received 10-20 requests for such a part, before they would have a few doors made. But none were kept in supply. So you are not going to find a new door someplace. In fact, about the only source of a part that was listed with the first letter in the SMR code of X, was cannibalization. If someone is parting out a uneconomically repairable gen set, you might get lucky.
The reason I listed item 31 was to show you a SMR code for stocked items. The parts that have an SMR code of PA, were stocked in the supply system, and the availability is much higher. These parts can be found online or from the manufacturer.
