Hey Harley,
I've owned an 1860, and an 1862 and both of those tractors had the front/top pins broke off. You see a lot of that style tractor with lange pan head screws or other methods of attaching to the mounting point.
On one of those tractors mentioned above, I used a very large but short woodscrew and was able to get it to anchor to the panel, feeding it through the mounting hole, back into the side panel.
It was a very common problem on that tractor version.
Good Luck,
Curt
