Yes they did. Same location as Willys bodies. Came with the plugs too.

Does someone know the correct bolts for these holes and where to buy repros. I have seen brass bolts with a head used ( from beneth the vehicle. I understand the correct ones are a slotted head bolt which looks more like a screw (ie without a pronounced head) and that is put in from the top

I am pretty sure early GPW parts books all list slotted plugs and they are steel. An old jeep guy told me you used the ignition key to remove them and my key does fit them. I bought a pair of NOS one years ago to fit to my GPW but later however, some doubt was cast on the supplier.

They were probably changed out in the field if the slot was worn down or just out of convenience since a slotted head can get chewed up if it's stuck.

This was hashed out before and the same number was used for the slotted and square plugs. :roll:

This is copied directly from the documents. If you compare the part numbers you will see there are mismatches on all three locations of the ¼” pipe plug. There is no way to prove the slotted plug or square head plug is correct for either, as the numbers are screwed up.

NO listing.

The Army really did a terrible job on checking the documentation for this part!

Now for myself, I have an MB-NAVY-MZ-1 Engineering photo # 2014 dated 2-8-44 taken at the factory clearly showing square head pipe plug for the floor drain. Under the List of Parts for drain plug for fuel and body WO-A-5120,, Pipe plug, ¼”.

I think Mark's documentation for everything but his MZ has pretty much layed it out for the Willys guys....look at the FUEL STRAINER, the GAS TANK and the FLOOR DRAIN plug info....the ones on the fuel strainer and gas tank we KNOW are Squareheaded....and Willys does not mention the type of HEAD on those items as Mark posted.....except when they came to the FLOOR DRAIN, where Willys stated it was SLOTTED.

Given the complete wild card status the MZs have....being a mixture of early/late and totally different assemblies in some instances, I am always suspicious when all the Willys Manuals say ONE thing and the MZ BOM says SOMETHING else....

So this may simply be a situation at Willys where they used the SLOTTED plugs all along and for some reason not know to us, they used a Squareheaded plug in the floor drain on the MZ and did not bother with a new number.....It would not be the first time the MZ has thrown us a curve ball when being compared to other MBs....

Of course if anyone opened a Willys Parts Manual TM to see what EARLY MB drain plugs are listed as....this might be easier to figure out.

FYI....if you are reproducing the drain plug socket and plug.....and you can BUY a standard 1/4" squareheaded pipe plug or you can ORDER a more expensive slotted plug and nobody knows what they had in the first place....after awhile everyone starts believeing what they see in restored jeeps as being "correct" if it won a prize of something....it was not that long ago that the experts believe that LATE WAR GPWs still had GPW-marked radiators....until enough evidence surfaced that they went to the same radiator as Willys did!

Weatherhead still makes the best slotted 1/4" brass pipe plugs. They do not get much wear as they are off the beaten path. Most of the WWII surplus MB/GPW Jeeps I have seen over the years were missing the plugs. Mine have not worn out (slotted brass) in 39 years of being removed/installed for wash jobs.

Hi guys,
I stil, back the slotted steel plugs for a GPW. Besides, the Ford Standard hardware book lists the part number and calls it slotted. There is a different number for a square headed plug. If I remember tonite, I'll list the part number.

Like Joel said, the plugs do not see any traffic where they are but I can imagine a steel plug with a slot would get pretty difficult to remove in time. I can easily see why they would be changed for something more practical.

Regards
Al

I could easily see a steel plug rusting into place and getting chewed up by someone trying to remove it, so steel is something that seems reasonable.
They did change from a set of brass glove box tags to steel maybe because of demand/shortages?

Now with the MZ, since it was ordered later into the war, it would seem possible that experience with a slotted plug led to a square pipe plug being requested instead.

I will now agree that slotted plugs were used in the Early MB.

This is in the List of Parts for the MB-Marine, Group 19-2D Metal Parts after Paint, page 7 of 8, dated 12-10-41:

A-5120 Plug - 1/4 - pipe thread - slotted (Front floor pan drain hole) 2 each

The list I have on the MB-NOM-12, Group 19-2D Metal Parts after Paint, page 7 of 17, dated 11-13-42 shows it as:

A-5120 Plug - 1/4 pipe thread (Front floor pan drain hole) 2 each

So, it appears the slotted plug was changed to the plug only sometime in the first 10 months of 1942.

This would dovetail nicely with the theory that the slotted plugs were brass as the change from brass to steel is some parts was mid 1942, however neither list of parts specifies the material type.

Thanks for some interesting posts. Does someone know where to source some repro slotted plugs?
thanks
