Yesss!!!!!!! Another engineer!!!!!!!! Finally!!!!!!!!!
Hehehe, I'm fixing up a Roadmaster myself, but mine's a '57. Everything seems to be pretty straightforward with it so far but the seat post is frightfully thin, I guess they didn't have The Whopper or super-sized fries during that time. Plus the bike frames tend to be smaller because the people were too, I'm giving the '57 to a family member who's rather petite.
As far as your Roadmaster, I'd say it's your bike, do with it what you want, but it's rare to find a bike as old as that in such good condition. Normally the tank is the first to go, it gets dented as soon as the bike falls down. Then the fenders get dented and removed. The chain guard gets destroyed and taken off. So if you have an old bike with everything on it you can also probably assume it has been well taken care of. You might be able to trade it to someone willing to restore it for all the other goodies that you're looking for in a stretched out bike like a cool frame, springer forks, and a wicked pair of apehangers, etc.
Once again, it's your bike and I don't want to stand in the way of your vision or ability. If you want to cut it up to make it fit, more power to you, that's part of what rat rodding is all about, but you might be able to get more than what you expect by trading it or parting it out on the classified section of this site. A lot of the folks here have a pretty impressive inventory which is always in flux.
