BFG Radial TA's vs. GY Polyglas bias plys

[danachevroletfor1967]

I agree with you guys that mentioned that you wish Goodyear would make a radial like the Eagle GT or ST again but with the sidewall white lettering reading Goodyear and Wide Tread GT. I would buy a set of those in an instant.
I have a question too. I currently have modern reproduction Goodyear E70-15's on my '69 Z. I like the looks of them but admittedly they don't handle or behave as well or as smoothly as the modern Goodyear Eagle GTII's I previously had on it. What are the correct alignment settings for the bias-ply tires I currently have on it now? I am thinking that the alignment should be adjusted for the bias-ply tires which was not done when I had them installed. Am I correct in this assumption? That might make the car handle a little better. Thanks guys.
