I got a line on a 1990 FJ60 for $2500.00. There is significant frame rust in spots, a bit of body rust as well. Mechanically the vehicle is in good condition, seats and interior are fair. Is there a source for a new frame if it were to come to that? I think the vehicle could be saved and it seems like no brainer if I can get the frame dealt with and not spend a fortune. I've never owned one of these older units, all of mine have been 100's and 200's. What other issues in the 60's do I need to look at and be aware of?
