Nice! Other than work to smooth the rear corner (where top of the quarter meets the side + the quarter extension),
any other effort needed to make the quarter mate with the quarter extension?

It looks like the '69 quarters are farther off in the tail light area than the '68s, as I had to add metal in a few places to make mine
mate up with the extensions. And yes, I need to start a build thread to illustrate that

I test fit my rear window trim and will need similar rework in that area to get it in the ballpark ( but I'm not touching it
until the dutchman is replaced).

Sure is nice to see all that work sealed up!
