the ignition is to the left of the steering wheel . The recessed lights look like someone hole sawed it and added them but at this point Im confused . The paint definitely looks old and not the same stuff they used in the last 20 years. Im interested to here more about the MD Juan tub you mentioned. Here is a pic of when I first got it. The seats were originally olive drab . Hope this helps. Thanks for all the imput

Sorry bud but thats a repop tub from MD Juan. There are no bow pockets, no top bow brackets for the front bows or rear bows. The toe board number is an MD Juan number and i bet the word "JEEP" is not embossed on the front of the toolbox. Don't be too disappointed because you probably dodged a big rust bullet with the original tub. 99.5% of people won't know the difference and will tell you thats a nice Army jeep...Thumbs Up
If I'm not mistaken the number indicates you have a 1999 production MD Juan tub. Go to the sub forum on parts and go to the BODY group section. There is a 33 page discussion on MD Juan parts. You'll learn a lot.

Original factory "VINs" and DMVs can get pretty "entertaining".  

I had my Dad's old 1947 Chevy 2 ton wrecker for a few years.  It was last registered in NC.  The VIN on the title was a combo of an engine number with the truck's serial number added onto the end of that.  And the engine number part was wrong as Dad replaced the original Chevy inline six with a GMC 302 inline six.  I had to sort it all out when I was trying to get one of the restoration guide packages that GM used to send out for free.

I'm not too bummed a little disappointed but is to be expected when you have a vehicle that is 69 years old. I was doing so research last night as well and everything pointed out to the MD Juan tube. Looks like i'll be welding some brackets , getting rid of the flush mount lights and painting Pickett gray as per the wifes request. I just hope this doesn't affect the value TOO much. Well I do appreciate the great responses and the help!!

 The only value affected, and the only one that matters, is what it's worth to you, or rather how well you like it, not expressed in $$.(Or how well the wife likes it Wink) Do what you want to. If you want to make it appear and function more like an original body, that's great. As has been said, 99.5% of the people looking at it will not know that it's not an original body. Only you, us, and your hairdresser will know for sure. LOL  It looks good, enjoy it!   BW

In the flat fender world, we often complain about the 'Fit and Finish' on these MD Juan tubs.  I've been lucky not to need a reproduction tub, but the truth is, without MD Juan, there would be far fewer old Willys Jeeps on the road today.  And that would be a shame.

You have a nice rig.  Enjoy the crap out of it!Thumbs Up

I don't want to blow your mind or anything but I got to thinking. Your engine number and the projected range of serial numbers that engine would put you in tells me that your jeep is a "lefty". Now I'm not going to sit here and explain to you what a lefty is but I will direct you to that topic in this very sub forum. It's a nice read just like The MD Juan thread was. I'm betting I'm right. Soooooo if you decide to weld on all the bracketry for the top bows and you're going to mount your spare again take some time to read about the lefty. Is it rare? You betcha. Is it worth a lot more? Sure. It's gotta be worth tens of dollars more than a standard CJ2a.

If/when you paint it, make sure it's really well-protected against rust.  Voice of bitter experience here.

I don't believe your MD Juan tub will have the proper spare tire bracing inside the driver side wheel well.  That said, you can get the "Lefty" braces.  It will require some surgery and welding.

Nope.  No hidden serials.

-There may have been a frame tag.  Gone
-There was a Willys serial number data plate on the passenger firewall.  Gone
-There was a body tag under the data plate on the firewall. Gone
-There was an ACM number on the original tub.  Gone

Based on your historical documentation, there is a good possibility that the engine is original...but even this can't be 100% verified.  The only way to know for certain is by comparing the engine number to the serial number on the data plate...which is gone.

I don't mean to throw up road blocks, but there are just times when the unknown stays unknown. Unfortunately, many of us have hit these same road blocks.

you can do whatever you want to your jeep. I brought up the lefty thing because your engine number made a light bulb go off. It would be a bit of a PITA to undo what you did already and do the necessary surgery but that's up to you.......no ones gonna know and with all the data tags missing you only have the engine to go off of.....you just seemed so fired up...might as well tell you everything...enjoy it and drive it like you stole it.Big smile

It's pretty apparent what you have is a cool ride you should put plates on and drive the balls off of Tongue

As near as I can tell your research on this +/- 70yo rig goes back three owners and 18 years.  That leaves the original engine to go 50 years to just get to the end of your research...  and I never heard you say "original owner"... just sayin' Wink

If we can conjure up all these unprovable what ifs based on an only an engine serial number, then my '46 2A was originally a 1952 Kaiser Henry J sedan, and I've successfully converted it into a late '53 M38.

Drive it.  Enjoy it.
