Are dart sports mostly gone

You can get new 3 point retractable seat belts for the duster with the dropper so its not cutting your head off. Doubt the fender braces do bugger all the steel is pretty thin....... if you want bracing u need to do full chassis connectors unless u want to crack your a piller lead joints.

Yep, just wish my '73 had come with the '74+ setup. They are cleaner than the aftermarket stuff just with the retractor hidden in the body.

The braces appear to actually ad some stiffening. I plan to add something as the project moves forward after it is driving. Should be able to look for a before and after.

Already done the subframe connectors and torque boxes. At some point it will get the lower radiator support bracing and hopefully something under the fender wells as well. I want it all. :D
