Thanks for the replies. As stated in the original post, I am aware of Coker, but they offer the actual bias-ply tires, which are not what I'm looking for.
PlumCrazy: Thanks for the referral to Kelsey Tire. Unfortunately, their website is down this morning, but I will keep looking.
So far, it looks like there are no radial reproductions of the original tires offered (Wide Oval or Polyglass). The modern BFG are great tires - I was just hoping for the 'old-school' look.
