Does anyone make a pre-bent 4 or 6 point roll bar for a '68 Dart? The car will primarily be used for autocross. I looked on S&W and I only see 8-points or higher. I also looked at Chris Alston's Chassisworks and they don't mention any mopar products on their website. Car's at a shop. The shop said they could make a cage, but it would probably be more beneficial and quicker to have a pre-purchased one. Thanks for your help.
