Yeah I may need to do some homework on my class restrictions. I'd really prefer to use the 2x3" tubing. And then of course I'd have to check the actual interference on my Duster, since we all know these cars have some variation. Especially talking about a '67 Barracuda and a '74 Duster.
**Edit**
The more I look at the SCCA classes, the more I realize that with the other mods I'm planning for the car I'll probably end up in a higher class than just the frame connectors will put me in anyway. Eh. Its not like I want it to be a competitive car, just a "for fun" thing anyway. The rims and tires I want to run alone bump me up a few classes.
