I want to use the tubbed chassis from the Chevelle. I think the wheelbase of the two cars should be the same, so I would use the entire Chevelle chassis, engine/trans, wheels/tires, etc.
I don't know if I'll even try this, as I don't have the GTO kit yet. I'm waiting to see if Hobby Lobby puts it on clearance because I've had it in the past, and I don't think it's worth more than about 7 bucks(if that). I've built the AMT pro street Chevelle, and really like it, and I have an extra one that I just want to find another kit to bash it with, so I don't have two of the same thing. I thought the GTO would be a good candidate, since it's such a lousy kit that I wouldn't mind throwing most of it in the trash, and it's the same size car.
I might just use another similar size car, Olds 442 maybe, to Pro Street. Suggestions are welcome!
