It is interesting that the civilian parts list do not show any numbers for the two screws attaching the access plate to the transmission tunnel cover, or the 12 screws attaching the leather pad to the tunnel cover. They show the cover as being an assembly: Part Type Code 23-04-103, COVER, Front Floor Transmission, Assembly, part number 950 939. To this cover attach 10 nuts that the screws from the left and right Floor Plates thread into: Nut, anchor, type E, S., pln., 5/16 in.-24, part number 148 232.
The 8 screws attaching the Front Floor Transmission Cover Assembly to the cab floor are shown in the civilian parts manuals under Part Type Code 23-04-113. First in list D-11091 as: SCREW, Front Floor and Toe Board, (hex-hd., S., pkd., 5/16-10 x 5/8 in.), part number 950 969. Then in list D-12004 as: SCREW, Front Floor and Transmission Cover, (hex-hd., S., pkd., 5/16-10 x 5/8 in.), part number 1197 042. Both 950 969 and 1197 042 are shown as never having previously been listed for Dodge trucks, both are indicated as being “parkerized” (pkd) rather than “cadmium plated” (cd-pltd), and neither mentions attached washers. I had a truck that still had the 5/16-10 bolts. They were more like a cross between an ACME thread and a wood screw rather than a machine thread.
These 8 screws are not listed in the 1951 parts list D-13864, but they reappear as a different number under the same Part Type Code in the 1953 Parts List D-14468: SCREW, Transmission Cover, (5/16”-24 x ¾”), part number 1093 705. Here, they have changed not only in part number, but also in size and length, changing from 5/16-10 (ACME thread?) to 5/16-24 UNF and changing in length from 5/8 to ¾. This parts list shows these new screws as being applicable to only the new B3PW and B4PW, not the older WDX, B1PW or B2PW. This would seem to imply that the screws changed at about the same time in early 1951 when the cab dash and pickup box changed.
My 1953 Part Supersedence List D-14720 is too new to show the change that apparently took place somewhere between 1948 and 1951 in the 19 screws attaching the right and left floor plates to the transmission cover assembly (120 741 to 1095 367). It does however list a change in part numbers from 950 969 to 1096 643. This does not agree with the 1946 and 1948 and parts lists where the change in the 8 screws was from 950 969 to 1197 042, or the 1948 and 1953 parts lists where 1197 042 then changed to 1093 705.
As well as the 950 969 to 1096 643 change, the Supersedence List also shows a change in 1197 042 to the new 1096 643, but I cannot find this new number anywhere in subsequent Power-Wagon specific parts lists.
If I go back to the old 1946 Standard Parts List, I find that it shows hex head screw and lock washer assemblies, but not in the 5/16-24 size used to attach the left and right Power-Wagon floor pates.
