1972 Duster , starting to tear into the build
About a 1/2 lifetime ago (it seems) I was commissioned to recondition a Shark-Tooth 71-72 Duster grill, and my payment was a ragged Shark-Tooth grill. I used a standard Duster grill that was damaged for parts (they were cheaply available back then). I used Super Glue to fill in cracks. I cut the horizontal fins from the donor standard grill. After cutting and slotting damaged horizontal fins from the target grill, I inserted them where busted Shark Tooth fins were bad and super glued them in place.
The goal was to have no visible cracks. This was accomplished with "filler" (super glue). I then had to paint the black horizontal fins, tape EACH AND EVERY HORIZONTAL FIN (this taping alone took about 1/2 a day!!), then spray the argent.
Basically, I tried to replace "broken" with "not broken" using a Dremel tool and super glue. The rest was meticulous labor and time. Since this was a 1/2 lifetime ago, the attached pic is the best I can provide.
