So, the dimension I'm looking for is the distance down from the window ledge to the the top of the large hole (vertical) for the 52 handles and the distance from the back edge of the door (horizontal) to the edge of the hole. I can use the old door cutouts for templates and then spot weld the re-enforcement plates into place. I'd just like to have them in the original spots and if that means I have to cut out the old holes, repair the skin and drill new ones, so be it.

I've purchased a set of large latches from these guys https://www.hotrodlatches.com/Large_...ge-latches.htm

The intention will be to modify it so as to make a bolt in attachment lockset that will work on the conversion. The next thought is whether to weld up the side of the door edge, recut the edge for the latches or make a cover plate and cut the area out, essentially making a bolt on lockset like the Altman uses. This would require me to cut out the latch area of the spare set of junk doors that I have (they are all bent up and toast otherwise) to make that 'cap'. This would make it a LOT easier to install the latches in and out, especially in the design stage (as they would just bolt in), but not nearly as clean install as the former idea.
