I'm new to the Mustang world. I just got a 1966 "Rustang" coupe with a 289CID. I know I'm in for a real learning experience. Any and all suggestions would be appreciated. 
Thanks,
Not sure if I'm using the wrong search terms here and on google, I'm looking for the spot welded fox body subframe parts behind the fenders. I see plenty o pics of rusty ones removed, new ones welded in. Where can I get new ones? I attached a pic , I can see all the individual panels spot welded...
