Thanks Darian, that's exactly the pics I was after. I wanted to see if they drilled the frame or had a different frame.
It can be seen in Terry's photos and the ones from the manual that the pins were closer to the centre in 69. What I think happened is that they were initially drilled to avoid the bonnet frame, but when viewed from the top side they looked out of place so in 70 they moved them outwards and drilled through the frame.
On the bonnet flip that I saw, as well as wrecking the bonnet, the roof was all caved in, so now that more have been confirmed I am leaning towards keeping the pins and moving them in, or at least some sort of hidden safety strap. Thanks for the offer JR but I will stick with correct year pins.
My listing had over 2500 views, 197 watchers and just 1 bid. That tells me that the market for this condition/price point is way too small so I wont bother listing again until I have re sprayed it and corrected the interior. Who knows I might be able to have a crack at that record price once it's done
Thanks for all your input.
