I'm not sure they'd survive getting cut down, as someone else said, they aren't the best castings. They appear to be pretty brittle. And you also haven't met my Dad, not running Mach 8s is complete heresy lol.
I'm guessing my best option is to get some made. I'll talk to some guys with access to the machine shop at school and see who wants to get them made as a class project. I think I can get the done that way. The thread was worth it for those sweet old parts store pictures!
