Where to find matching numbers.....
Core support drivers side on top usually under the antifreeze sticker. Trunk rail drivers side under the weatherstrip. Both require paint removal to see them unless they are original, but still require weatherstrip and glue removal, most sellers don't want that to happen. Passenger side of engine just above oil pan rail on a 3/4"x3" flat pad machined into the block. Passenger side of trans on bellhousing of automatic and side of 4-speed near the front on machined pads. Fender tag also.
