Marc, I would opt for the BFG RWL's. The radials ride SO much nicer than any of the bias plys. The alternative is the redline or white line radial, but if you're going radial anyway, I think the BFG RWL's are a great choice and value.

Just a sidenote, raised white letters were indeed available on 1st Gens. They were used on some 1969 Camaros and 1969 Trans Am's. But for a regular Firebird, you only had a choice of either red or white stripe, or blackwall for base.

I have 14x7 Rally II's with BFG RWL's, and I also have a set of 15x7 Rally II's with Firestone Wide Oval red lines.

I like how the 15x7's fill the wheelwell too, but the bias ply ride is awful. To keep a stock look, I modified a set of 15x8 trim rings, which have the same dish as a 14x7 Firebird Rally II trim ring. I switch back and forth occasionally.
