Thanks
The car is in the LA area and i had a shop down there check it out and the rust had not spread to the rockers. In fact he said it was the only spot of rust he could see. Of course that doesn't mean everything.
I will have to get some pictures today of the rusty area.
I checked out the local '75 on cl. The care is pretty sound, the dealer is pretty sketchy.
Thanks, I will try and get some photos up.
