MuuMuu101's 68 Dart, A Learning Process...

that seems kinda skimpy on the companies part to charge 45 big ones and then you still have to drill it.

when I did mine I cut where the reliefs need to be into the 1/4 with a cutoff wheel then pounded it in to clear the cap and welded the cutout area to seal the 1/4......if that makes any sense. That way the cap is a bit more flush looking like on a cuda.

The website says the 3 holed ones are supposed to work. The only way I see it working is if I drill and counter-bore the 4 holes for it to mount to the quarter panel and screw the adapter down, then drill tiny holes to screw the cap onto the adapter so it isn't raised by the screw heads. Or, I can drill 2 holes into the cap and 4 holes into the adapter to just utilize 4 screws.
