Am considereing buying a 'typical' $1000 Michigan Jeep Wrangler YJ (1987-1995) as a beater/summer toy/whatever. Am very familiar with Michigan rust in general. My question is: If/when the frame/spring mounts/body mounts are rusty, are these Wranglers fixable with frame patches, welding plate, etc? Or once rusted I should run away screaming. Don't really want to consider a new frame.

I'm considering cheap, that's why a YJ and not a TJ.

Any experiences?
