Yeah, I have a homemade top too. It looks like a very good fabricator started it and then when it was 90% done a chimpanzee with an angle grinder got a hold of it. Its expertly welded, all the sheet metal is done perfectly with a shrinker/stretcher, english wheel etc.
Then someone ground off the standing seam on top of the cab and zip screwed the roof on and tried to "glue" it with bondo. The windshield-to-hood hold downs were sawn off and the windshield frame was booger welded to the roof. Then the welds cracked so it was brazed. Why didn't they make up the pins that make the roof go on like it's supposed to? I can't make sense of it.
I want a canvas top too, but my homemade hard top can be "finished" to work like a real one. I'll probably finish it, insulate it, and keep it as a winter roof.
I got my engine to turn over too... but then decided I will not be using it. It's 850lbs, makes like 78hp and gets 5MPG. Since the truck isn't in good enough condition to make a "period correct" restoration, I'm less concerned about re-powering it. I want to use it, not just for parades. I want a 4BT but I'm on a small block chevy budget. I'm making the mounts and everything with the future 4BT in mind though.
Soon I'll start taking my engine apart to see what's good/usable. I saw the manifold has a crack. Some things I will put on that evil auction site to help finance the build but if you need something specific off it, let me know and I can put it aside for you.
