I have two friends that used Art Morrison chassis, one on a 57 Chevy car and one on a 56 Chevy pickup. Both are very happy and the object of my jealousy. I'm from WA. so Art Morrison would be my first choice if I had the money to go that way. It would be great to visit the factory and pick out the options, then come back and load it up when it was done. I imagine there are Roadster Shop users who are happy with their chassis as well. Either way it should save you a lot of headaches.

Best of luck with your choice,

B
