Quote: Then most of the red lines were Good Year "polyglass" not Speedways. F70X14 to be exact. See 6bblgt's post for additional info
This is the info I'm trying to decipher. IF I go with redlines and my car is Sep '68 it seems to indicate Speedways. Then it goes on to show the optional and late available tires. Are Speedway redlines the only choice or early build or is the Polyglas redline an early build option or just another "late build" option?
