It would appear Pontiac made the Ch**y frames then.

yes, and some CHEVROLET ones as well...

I looked on a Beaumont frame today and found the "hidden VIN" we always hear about. It was on the passenger rail just behind the trunk floor body mount (second mount from the back) I had never actually seen one before. The whole VIN was not there, only partial. Interesting to see though.

does pon mean pontiac michigan plant?
the rest is definitly a date code not a vin code

I talked to a guy at the CanAm Chevelle show in Grand Island Now York a few months ago about his 67 Beaumont SD. He is the original owner. When he did the restoration he found the same PON stamped on his frame. James

I am pretty convinced there must have been a frame plant in Pontiac. Seems to me the GTO restoration guide list 2 locations that A body frames were made. Somehow I think one was in the midwest (not PON)

I found an update to this in the GTO restoration guide today.

very good    I wondered that  lol

one for the other side

I know this is a old post but Just looked at my 69 Beaumont frame and has the following ;

Part # 3943331

5-1-69-2  

There is no PON But there is  the letters  (  Yes ) looks like it was stamped over  one of the factory holes in the frame so blocks out the other letters.Y could be a V not sure. You can just see remnants of two other letters.  mabe Hayes.

I assume the 5-1-69-2 is May first, 1969, shift #2. YES is anybody's guess!

looks like you have a late built car? second latest ive seen other than clints,june car

what date does your cowl tag say?

Lower left hand corner of cowl tag  is  5C   would that mean third week of may ? If so would be correct for the frame made three week before.

Ian

looks like yours was made 2 weeks before clints
