GP wheel base lengths???

Can someone tell me or point me in the right direction for wheelbase lengths of GP35, GP40 and GP60 locos?? Thanks!!

 

There are only three wheel base lengths. Someone will have to help me here...
GP7,9,18, and 20 are all the same.
GP30 and 35 are the same.
GP38, 40, 50, and 60 are all the same.

 

There are more than three. GP60 is different. A lot of books say they are the same but ar not correct.. You also have the GPP's.
GP40-2 59' 2"---34'
GP40P-2 62' 8"---37' 3"
GP60 (6) 59' 9"---35' 1"
