Help with seat location in Tiger Stadium?

Hi everyone...I'm very excited to be going to the Florida/LSU game but am totally confused about the tickets I just received. I received 4 tickets...all are in section 643, with three in row AA seats 1-3....but the 4th is in row Z! (seat 1)...I have no idea how Tiger Stadium is laid out, but it would seem to me that row AA would be at the bottom of the section and row Z would be at the top. Am I wrong (I hope)? Can anyone tell me if my seats are really far apart or is it possible that row Z is actually right next to row AA? Thanks in advance!

 

row AA is right above row Z
A-Z
then AA-don't remember how high they go

 

Here's a seating chart, which will also give you a feel for your view of the field.

First, glad you could make it to the game. Come tailgate with us.
Second, those tickets should be next to each other but high in the upper level. Bring your binoculars.

 

thanks everyone!
