Rather than request Joe Friday for additional scans of the drawing, I'm sure if the drawings are the same as the GPW drawings, which depict the milled channel, then posting additional scans is moot, because the drawings are identical.

In the blue print of the Willys filler there is a note that the weight should not exceed 3lbs and 14oz. Would this be why there is a recess in the wood to make sure that they did not exceed this weight?
I will weigh the Ford one I have here to see what its 75 odd year old dried out weight is. and if I get time I will take my Willys filler out and weight that too.
The different woods would have different cube weights and the heavier wood may be recessed and the lighter wood not.

Yes, the only reason for a groove would be to reduce weight. Otherwise it serves no purpose. Also note that the M38 wood filler does not have a groove as they were not trying to keep weight down, as they were in WW2. Gliders and all....

Could you post the portion of the Willys drawing that details the groove?

Many Jeeps were retrofitted.

Last night I weighed the Ford style filler I have here and it weighs 3lbs 3 1/2 oz.
It has some very small bits missing and a very small amount of friable wood on one edge where the dry rot has attacked it so it would probably be 3 lbs 4 1/2 oz intact.
I cannot believe that these pieces of filler were made from kiln dried wood, NOT when they were going on a vehicle to be used as the jeep was designed to be used, and knowing the amount of energy needed to kiln dry the wood.
Now if this piece had been made from air dried wood it is highly likely that the weight could have exceeded the 3lbs 14oz limit with that groove NOT machined out.

Glad you asked, I still think your Jeep may have been a retrofit

A lot of MB, M-38, M-38A1 and CJ 2A thru CJ-5 Jeeps have crossed my path since the 40's when I first sat in a new 45 CJ-2A and the first surplus WWII Jeeps and trucks we sold and serviced, They were an instant hit and launched the beginning of am longtime MV and Jeep hobby. next were years of servicing new and used Jeeps followed by Army training as a Wheeled Vehice Mechanic. Back then there were a lot of WWII/Korea civilian mechanics with their WII MV experience still fresh in their young minds, the Army instructors were WWII and Korean War types eager to share their WWII Jeep and MV experience.

The source for the Torque Reaction information? I can't actually pinpoint it as it may have come from dozens of sources such as young WWII mechanics with their experience fresh in their young memories, the"NABHOLTZ revised" book, articles from WWII Army Motors, or the Lloyd White massive 5 volume "the Evolution of the Willys Overland MB Jeep" sitting on my coffee table. That set may be expensive, but it is worth every nickel.
This is an exciting hobby, if you are a serious student of the WWII Jeep, Lloyd's books are a must.
Volume 2,Page 45 of LLoyds set explains the A-6157 TORQUE REACTION SPRING KIT from a Service Bulletin dated 1 September, 1942.
I have been very lucky to have been surrounded by my hobby in both Civilian and Military life and enjoy sharing it with all in the hobby.

Depends on the wood species; if made from oak or birch, as indicated above, then it would need the groove to make weight limit.
If made from Poplar, like Joel said his was, then it wouldn't.
Yellow Poplar (actually not a true poplar but that is not important here) weighs only 58 percent of white oak or yellow birch.
Finally, my Forestry degree paid off!

Two of my neighbors are Forestry Professors at U of Maine, will ask them to confirm my GI Issue filler is Poplar.

Yet another interesting thread threatened to be delrailed by long winded non-answers to unrelated BS. :roll:


This is why I prefer the Factory Class facebook group. No BS and it's heavily vetted. No Bendys there.
