These pieces attach to the inside rocker panel to cover the
wiring and fit between the sill plates and the carpet to protect the
wiring. These can be used on 70-81 Camaro and Trans Am. Currently
there is another version available in metal, but are prone to back
order, and a lot more expensive.
These units are made of aluminum and will never rust like the GM units and other reproductions do.
If you are need these, this type is the best option!!
