tire options left in 14 inch ?

Take a look at Coker Tires. They specialize in classic car tires so they have a good selection of 14" radial tires. They have several widths of white stripes or red stripes if you are trying to match the original look.

I bought a set of 14" Maxxis from their site for my Barracuda and got a 7/8" white wall. I got the widest tire that would fit on the factory 4.5" wide rims. They were able to ship from a Western warehouse location which saved a lot of money on shipping charges.
