Some rough notes while going through some factory documentation I was lucky enough to receive:
Option G66, "Air Booster Rear Shock Equipment", gave you a shraeder valve at the back license plate where you could air up your shocks
The 327 was still used for export models (right hand drive)
There is -supposed- to be a displacement sticker (they show 396) over the 1-Team Tonawanda engine sticker on big blocks
The hood light DOES move side to side. Driver side for small block, passenger side for big block and inline 6
The oil change sticker follows the light (if equipped) and the sticker should be upside down for easier reading
For the european market option T94 cut amber signal lights into the rear metal bumper
There is support for 3 speakers, 2 in the rear and one in the front, depending on the combination of stereo tape player and FM stereo that you had
Speakers are shown with a backing box on the trunk side, but I've never seen that
Per North, all but the GP had speaker grilles - the GP had a mesh style package shelf instead
A rear power antenna is listed in the front RPO list but not in the detailed option instructions, so may not have existed
A rear manual antenna (like my 2+2 now has) is detailed under option U73
There's a master RPO list up front that doesn't necessarily mean they made it, but at least they had a code for it. It lists electric rear window defog, for example, which I think was Grand Prix only that year, if anywhere. But there are option codes like "U30 - Aux Gauge Panel" that I'm not sure what to make of.
Anyway, that's just from my first look, I'm sure others will have more input!
I searched but couldn't find ANY example of european export cars of that vintage with amber rear signals, let alone 1969 Pontiacs. I bet they're ugly though, based on the drawing!
The 69 2+2 I grabbed for the chassis had the G66, "Air Booster Rear Shock Equipment". The shraeder valve was still there, and bits & pieces of the steel lines to the shocks, but the air shocks were long gone. There were a couple brackets that I suspect held the transition from steel to flexible lines. I think I've got those brackets somewhere.
Re the backing box in the truck for the rear speakers, my 70's have that. There's a small bracket hanging below the speaker that extends through the middle of the backing box so it can be attached. On your 69's, is that bracket present?
