Erratic Keypins

I'm working on a grand action where the keypins appear new/recent and are at all sorts of angles - many leaning forward and actually catching the key mortise edge. 40% of them you can wiggle quite a bit with your finger (like 1 mm movement at the top easily). Wood around pins feels almost spongy - like someone treated the darn thing with the pinblock dope of yesteryear (but no stains - don't really think anyone did that). Most pins pull out quite easily. This thing is a mess. I've been bending a few pins, etc., to make things function, but this is otherwise a very nice piano and these pins are total BS. I can't feel right applying 73 bandages to this instrument.

The only thing I can think of doing to make things right is to either replace the key frame front rail and drill new holes or plug the original and redrill. Anybody tackle this task before? Anyone have any other wise ideas (constructive-wise, not smart-alleky-wise!)?

Thanks. Scary pictures available upon request.
