How many torque boxes does a '70 Mach 1 fastback have? The reason I ask is because Im buying all my sheet metal and while under the car I noticed there was rust in the front and rear of the floorpan where it slopes down (the pieces are connected to the floorpan, not the floorpan itself). Is there a drawing/diagram that shows all the body pieces of a 1970 Mustang? I can tell what pieces need to be replaced, but Im not sure what they are called! Thanks.

All 70 Mustangs had 4 torque boxes, the front 2 joined the rocker to the front frame rail, the rear joined the rocker to the rear frame rail, at the leaf spring eye bolt. All Mustangs had the rear box, but until 67, only convertible had the front box. In 67, coupe and fastback cars got the left-front box, and 68-on all had all four.
