good find, I was at an FBO where I got most of my flight training, they did repairs as well, they had a whole wall of parts they had fixed on planes and all these parts were corrosion just like yours. Its amazing how alumn will just fail like that.
On the plane I have now there is alot of rusty bolts, I found instances where I'm concerned if they used AN bolts. I've checked every bolt for an X I can see. Seems 2 people built that plane, the second person just threw things together and most of that is at the firewall. So I figure someone did the fuselage (including control sufaces) and someone else finished it with the wiring and firewall forward. I JUST KNOW this was a flying plane, it originally had the retracts, you can see in some of my pictures the PISS POOR fiberglass work done to cover the holes. Can't wait to be done with this baby.
