Thanks in advance. Almost finished with my 69 Z-28 restoration and would like to put the most correct bias ply Repo tires on it. Some books say the Firestone E-70-15 Wide Oval Sport Car 200 and other books say the Goodyear E-70-15 Speedway widetread GT. Which would you guys recommend and any ideas on the best place to buy them ?? Thanks Team Camaro
