Rob,
 Woohoo,, Awsome,,,   is that your Car ? other car ?(not the '69 obviously-lol)
 I hope thats on a closed road, lol -  cops would love to find yas doing a break race on public streets
 
On THAT car it doesn't look like  POSI-traction -- , if it is Posi-- the right  tire has more go to it,huh ?,as that's most of time the 'drive-tire'    But theres nothing like   2  long fresh strips of rubber down the road from a car with Posi ---sill hot if ya touch 'em ,, lol       thanks alot  for the pics ,,, how'd you know,,,I love that kind of stuff! 
Also---Good-Year or whatever tires you use - Must LOVE you and that F-body Club!! lol   The service reps know yas by name? lol  (just kidding)  They Must go thru a lot of stuff- though ,,, that's  fun to do,, But not a lot (unless you wanna repair cars a lot), don't beat on a car that awsome, But don't drive under the speed limit either ......LOL --- 
Now get in the garage and work on that car!  
Thanks again!
