Summit has the Firestones
http://www.summitracing.com/int/part...5970/overview/
and also Goodrich and Firestone Deluxe...
BUT
Coker makes the Firestones, they are the same price direct from Coker as buying from Summit, sure there is no freight from Summit, but Coker probably has a dealer close to you ,where they can be delivered and probably fitted. Coker also has tubes, wheels, wheelnuts etc etc for your Model A.
In fact Summit probably drop ships from Coker.
I buy direct from Coker , have them delivered to my shipper on the West Coast ,( to go to New Zealand) Coker only charge me $20 a tire and I don't pay any sales tax!!
