which one do you like better? PLEASE help me...

Dusterdan,
Check out ebay, there is a 1970 B5 colored Duster up for auction with the second style seat/covers....will give you a great idea of how it would look when finished. I have had both styles seats and covers and both are hot in the summer but I would chose the second if I was doing a bench seat car. Love the looks of it. Good luck with your choice!
