Well, I suppose it's all in how you look at it, and what you consider "easy". With the abundance of these cars still on the market, (and it's a buyer's market right now), I just can't see why you'd want to go through that kind of effort when it would be far easier to buy one w/ a hard top. Again, that's just my opinion. If you think it's a worthwhile venture, and want to spend a couple of grand doing it the right way, then you'd at the very least have an interesting topic for conversation around the hot rod crowd.
One example above was done due to the car already needing body work. Not because he had a wild whim. Also, I've rarely seen cars with lots of body filler/bondo, that did not eventually show signs of it. Unless of course, you're paying top dollar to an extremely skilled body man. But then again arises the issue of cost. Lots of money unnecessarily spent.
Anyway, there's no need to debate this. It's certainly up to you to do what you feel is best for your situation. I was merely trying to offer some food for thought, and logic to support it.
Let us know how it goes. It'll be interesting to hear/see.
Best wishes.
