Yes, I made what Dodge should have built. I'll post a build on it shortly. I bought it as a 69 GT 318 Dart last thanksgiving. Some one started the project using a 72 doner parts on it but I took everything off of it and started from scratch. The work that was done was far from unusable. Here is what I started with.
How much front/rear adjustment is there on convertible tops? The reason I ask is that the distance from the bottom of the glass to the dutchman panel varies quite a bit on cars I've seen. Some have a lot of material below the glass like yours but others have a lot less.
I know the last bow has to sit 24 1/2" from the dutchman panel. The variation may be on the supplyer of the tops. My top came from Legendary Interiors.
