A body hood hinges WTF?!

I agree, the threaded hinge studs sound like a good idea. I haven't had any problems with any A-body from anything other than rust, and that was only one car. I do know, as someone said, that if you get a little rust on the pins for the hinge, that it gets sticky and can tweak a hood hinge pretty easily.
Someone make a day trip out there and bring some extra hinges. Nothing worse than having to do a two man job with one man.
