I went to get a throttle body gasket for my GSR and it doesnt match how do tell what throttle i have..

 

gsr throttle bodies have threaded bolt hole on the throttle stop for their own cable bracket just to the right of the throttle bore. i'm assuming b16 and b18c5 throttle has no hole on the throttle stop. not sure if gasket are the same. maybe someone else can chime in.
