Why cut half the roof off the car? If you want to put some power in it, better brace the body and frame. GN guys have busted windows and popped out t tops.I am actually building (as in converting to) a stick car right now. I plan to put a T-Top roof on it. Now, if a nice person were to just sell me his it would save me a lot of work. I'm sure Santa would put him on the nice list.
Seriously, If someone knows of one of those that become available in the future, please let me know. I am an avid Pontiac collector (as my budget allows of course) and I would love a real 4 spd car. T-tops are a plus but not a requirement.
