most states nowadays won't title anything that old, all you can get is a transferable registration.... The body tag, ( frame on Kaiser, Firewall on Ford, Trans hump on AMG) is not a vin#, its an assembly line sequence number and may be duplicated on other jeeps. Spots to check for the military reg/vin# would be the sides of the hood, under the hood, and on the dashboard on the passenger side. if you can find that number Muttguru can probably provide you with the rest of the info for your dataplate.

In Texas, we can get a bonded title on vehicles w/o a title. We get a packet from the DMV. It is sent in with all the info requested, the bill of sale, appraisal, fees, etc., and a bonded title is issued if they do not find any other claims on the vehicle.
Since my 151A2 had no vin#, I took the contract number off the engine data plate, made a tag with this number (which is now my title vin#), the manufacturer, and year (This was determined by using a number in the contract number as told to me by John at TNJ Murray), and fastened it to the firewall. When I sent in my paperwork, this contract number was listed as the vin#. Mine is now legally a 1973 AM General M151A2, VIN# 500xxxx.
Basically, we can use any number if there is not one. It will go through as long as there is not another vehicle listed with the same number.
Then, as far as the plates go, we have four options: register as a regular vehicle, register as an antique/classic, register as a former military vehicle with plates that show this, or register as a former military vehicle with the hood number as our registration number without plates.
I don't know if this is any help in your state, but you might check it out.
