C2 Rear Valance why 2 Holes on each side?

[Alan D.]

The rear valance and body panel very often have 2 holes available for mounting, (or always)
Where these double holes only on St Louis cars ?
Are they on side exhaust cars?
Are there specific years ?
Why are double holes even needed?
Do the replace GM parts have them?
And many more ? on these

Often wondered about the double hole & after asking around no answer yet,
so it's an open subject.
Your input please!

Alan,

My AO Smith built late production '65 also has two (2) holes in the rear valance panel and both left and right side rear fenders. The car has rear exiting exhaust.

Hi-This is 66 car # 3795 (AO body)IMG_20230324_145658505.jpg
Looks like the valance has 2 holes, but the fender only has the forward hole

Alan, since the rear panel was installed during original painting of car and was held on by only a few bolts, it is unpainted behind the retainer tabs. The second bolt hole was used to space out the panel so the edges could receive paint. The panel was then removed prior to body drop. The panel was installed after body drop with new unpainted bolts and fitted to the correct position using second hole. PS this is just a WAG on my part

The thread on this topic that Alan started in 2010 includes reports by some owners of 64, 65, 66, and 67 that only have one hole per side.

Re: C2 Rear Valance why 2 Holes on each side?

Gary, the various number of holes may be that these holes were an assembly line aid for workers, maybe used to support valance so the tabs weren't damaged by flexing, yes my old 64 had one on one side, two on other, this seems like an on going evolving aid to line workers, with variable hole numbers etc. Alan's question still stands.

Thanks Gary, forgot about that one back in 2010, but after 13 years seemed like it needed to be asked again.



So as I said back then:
"Thanks to everyone for their input. I've been tracking the years v hole and just nothing lines up! So at this point I think its safe to say we do not know! "



Some pointed comments from back then;
Hinckley : St. Louis vs. A.O. Smith shouldn't be a variable - there was only one supplier for quarter panels, and he supplied both plants with the same pre-drilled panel.


Hanson: The panel was hung with a few bolts as the body went through all of the paint operations. Then the panel was removed while the body was trimmed. After the body was set on the chassis, the panel was reinstalled. (not necessarily the same panel)
A O Smith bodies were painted without the panel in place.

Looking over a 63 candidate for Bowtie, it had ONE hole. Then also saw another 63 with ONE hole.
So it appears that ONE or TWO is to be expected, just to update.

Re: C2 Rear Valance why 2 Holes on each side?

It is understandable why there might be two holes on a 63. On the valence the attachment part was bonded to the valence. Depending on who bonded it together, there was no guarantee anything would align as holes were drilled. On 64 to 67 the attachment part was part of the valence, thus it would have aligned more easily to install the bolt. I'm not sure why a 64 - 67 would have more than one hole per side.

Also, the 63 right and left bonding strip on the rear-quarter had a different part number than 64 - 67.

Gary,
What are other characteristics,

St Louis or AO car
Side exhaust car
Number of holes on valance
Build date (E,M,L)
