a 1970 mustang didnt have them?

 

Yes a 70 Mustang should have them. The 65-66 coupe and fastback did not have them.
They are metal boxes that are welded to the sub frame and the rocker panels right under the front of the door to stiffen up the chassis. If yours have rusted out, you need to replace them at the same time as you replace the floors.

 

its not hard to do its gotta be welded on a torque box both sides and subframe connectors will make it good and stiff
