Even leaving the old tonneau in the sun on a hot summer day would not relax it enough to again fit the car. The first studs to no longer fit were the outboard studs on the rear cowl.

I hear you Jim, but if all the tops and tonnaus are the same age, you would expect them all to be shrunk, unless perhaps differences in weather exposure between them effected some more than others. I also seem to recall it was one outboard pin that wouldn't line up on some and another outboard one near it would fit (?).

If it's the same car I'm referring to, the main issue was not the pins sliding in, but the leading/front edge of the plexi was interfering or overlapping improperly at the windshield frame. This is one of the very few cars that I'm aware of in recent times that was restored using almost all original parts (owner traveled across the country to work out deals getting what he needed), if that gives you a better idea.
