Our dad did back in the very early 80s. One of my earliest memories was of him meeting with the guy in our garage when he took all the measurements. I remember a few camping trips where my brother and I rode on a platform he had built in the back. Not at all comfortable on the Sunday afternoon ride home with a wicked bad lake reflection sunburn.
It was a pretty interesting disassembly today. According to my dad, he'd never had any of the body apart before. When he bought it in the early 70s it was orange. He painted it burgundy shortly before I was born. The paintjob didn't come out very well because of some problem with shrinkback. He had a body shop shoot it black and that's the color I've always known it.
It was flathead powered when he got it and he put a 283 in it with a bellhousing adapter. I still have that part. Later, he had a fledgling hotrod shop install a TH350 and 9". I was looking at some of the welds today. The guy was pretty competent with the oyyacetyle welder.
