FORD TUB DATING FEATURE

Post by Chuck Lutz » Thu Dec 21, 2017 4:48 pm

Ian...and you other VEP GPW guys, listen up. I discovered something the other day and after a conversation with Tom W., we have come to the conclusion this is an Early/Late identification feature. While true Ford tubs do not have a number like the ACM tubs due, we have been generally able to tell if a tub is original to a frame by virtue of several mfgering differences.

So, here goes. If you have an original Ford tub, be it a script or a slightly later one, can you check to see which style of a captured nut plate is spot welded to your tub for the left front leg of the driver's seat. The one in front of the gas tank well.

Here is what the consensus is so far...
1) April 42 GPWs have that rectangular plate with the clipped off corner spot-welded perpendicular to the tank well...

2) August 42 GPWs have that plate spot-welded on an angle to the tankwell....

So, to help with determining when this change occurred and by that, enabling Tom and others to narrow down the production date and thereby tell if a tub is original to a frame in the middle of 1942, can you guys post the answers to the following questions. Please keep this to what appears to be ORIGINAL Ford tubs between April and August 1942.

1) Does the glove box have a FLAT floor?
2) Is there a gas can strengthening plate spot-welded to the rear panel of the tub? (PS....the plate came before the carrier was added!)
3) Is it a "script" FORD tub?
4) Is there a trailer socket inn the tub? (original, not a hack job)
5) Are the reflectors on the rear panel off-set like later tubs that DID have a socket or not? (PS...the off-set mountings came before the socket was added)
6) Can you confirm if your tub has the "raised rib" behind the tool box lid?

BONUS QUESTION!!!

The small plate that the captured nut for the left front bolt on the driver's seat has a "clipped corner". Have you figured out WHY that is?

Hi Chuck; you might also look at the ridge on the small flat area between toolbox lids and rear panel
