My original Challenger had a simple aluminum gap cover. I liked the looks of the molded three piece fiberglass version so I decided to upgrade this part during the rebuild. The part comes in three pieces and is gel coated black. I built some aluminum angle pieces for the cover to screw to.
Fitting the gap cover in place. Lot’s of trial and error.
This picture shows how much I had to cut off in order to clear the reduction drive in the rear.
