I remember a Jeep in Red River , NM in the mid 60's that had a spare tire on both rear fenders.  So long ago and far away.

It's not obvious but the 8-1/2" dimension is incorrect.

Okay, here is my theory as to why the template is made backwards...

Perhaps the dampener block was conceived during the 2A "Lefty" period.  ???

If you read the first "Lefty" Service Bulletin,  they were committed to making this a permanent change.   Only later did they realize this wasn't a good solution, but never re-drew the template.  Then, they decided to just install the block at the factory, so they didn't really need to re-draw the template.

Again, just guessing.

I looked at the dimension drawing from that #49-24 service bulletin (as shown on the CJ3B page) and the glaring mistake (to me anyway) is that the drawing shows the DRIVER side with dimensions, and the dimensions on the drawing reference spare tire carrier holes for placement of the dampener block. Of course, the driver side will not have carrier holes, so even if one didn't notice the drawing is of the driver side, and went to drill holes, the lack of spare tire carrier holes to reference from would have flagged one not to continue.
In my case, I'm leaning toward them being there since new. Not sure what I'll duplicate.

According to my notes the vibration damper was installed at the factory beginning at CJ-3A 31245. I can't seem to locate the source for this information at this time.

Service Bulletin 49-57 is the source for this information.

Then there's the possibility it was simply personal choice. Some people want things for no other reason but "I want it". Maybe they though it looked better with two wooden strips, one on each side. People do thing for odd reasons and 50 years later we're left scratching our heads...

I've also seen a 1951 CJ-3A with only one of the vibration damper holes punched in the right side panel.

Take a close look at the drawing included with Service Bulletin #49-24. One of the dimensions is incorrect.

So this Willys is possibly the proverbial two headed Nickel. :)  Squidtone, I don�t know how you feel about this, but I might drill both sides... just as a conversation starter. :o

Bob,

With that information, is it possible that they did drill the driver side for some reason?

I'd guess that during the process of making those side panels the left and right sides begin as the same cutout blank. The holes were probably punched early in the process while it was still flat, before the flanges were formed. Somehow that left side blank inadvertently ended up with the punched holes for a vibration damper.

Ahh, a good question.
I looked and nope, I see no mounting holes for a spare carrier in the driver side.
The remnant carrier bracket holes are still there on the passenger side.
But I'll add this oddity to the list of things I'll keep an eye out for on other early CJ's...ha.

Is there any indication that the spare tire was moved to the driver  side at some point?  Perhaps after the passenger side started to disintegrate?

Thanks Hawk
Yes the more I ponder, the more it doesn't make sense (factory holes in driver side).
I looked at the pictures I took of my Jeep when I picked it up in 2006 (before I stashed it away), and I see that the passenger side still had stovebolt type slotted screws with rusted nuts in those holes, with the wood presumably rotted away. The mirrored holes in the driver side were there too in my pictures, but of course no screws were in them. I suppose the reason is lost to the mists of time why someone (or dealer) would put in holes.
I do wonder if ever these blocks were installed at the factory particularly in the later CJ3B to CJ5 years.
I'll at least put on the passenger side block.

Squid,
Before you make this decision, I would refer you to Service Bulletin # 49-24 dated May 20, 1949.  It is directed to "Distributors and Dealers".

It reads as though this was not a factory installed part, thus was probably not drilled at the factory.

Here is the major portion of the bulletin...



In order to reduce the vibration of the spare tire on the Model CJ-3A Jeep, a hard wood spacer can be installed on the side of the body as per the attached sketches. The thickness of this block depends upon the size of the tire used on the vehicle, whether 7.00-15 or 6.00-16. The thicker block is used with the 6'00-16 tires.

Where vehicles are used in rough territory, it is suggested that you interest your owners in the installation of this vibration dampener. It can be purchased under Part No. 671158 for the 7.00 tire and Part No. 671157 for the 6.00 tire, or made locally and installed in accordance with the template attached, by using the following parts.



The actual service Bulletin can be found at the 2A Page.  It includes a couple drawings, including a template to use for proper placement and drilling.
