A public thank you to 'American Revolution' for the tip. Local transmission shop had a wrecked 74 Blazer that was being parted out (ie was available for scavenging from

). For $120 I got a clean hood, Bolt in Roll bar (more on that later), Interior door handles, Weatherstrip for doors and took a reciprocating saw to the cracked top so I now have enough of a top to try to create a half cab in future.
