Top replacement?

Today I found rust along the drip rail under the seam sealer that goes through to the inside in a few places. There are also some pretty well rusted areas at the bottom of the A-pillars on both sides and some rust in the plenum of the cowl. I have already replaced both rear quarters from the door jamb back, the complete trunk surround, package tray with the bottom of the window surround, floor pans, trunk floor, partial and complete wheel houses, upper shock mount, half a rear sub frame, the cross panel under the rear gravel pan, etc. I was just getting ready to finally put the car on the rotisserie after I got the dash out and front end removed, and the K-frame out. Waiting for my torsion bar removal tool from Mancini for that. Today’s discoveries were a big disappointment. I’m not even sure how to go about replacing what needs to be repaired. I have a donor car that is a two door post. It’s an Arizona car and has pretty much rust-free the parts I would need.

My car is a ‘65 Dart GT with the 235hp 273 and a four-speed. It’s also an original yellow car with the black vinyl half-top. I’m trying to make it a clone of the Dart GoGo I had in high school. I’d consider buying another car and just junking this one, but 4-speed 235hp ‘65 coupes are extremely rare. I have a lot of parts for this car (and for my ‘65 GT 235hp/904 convertible), Kelsey disc brakes, tabbed LCA’s, sway bars, etc. Should I just junk my coupe, or go a little farther? Any advice or suggestions would be greatly appreciated.
