Remember that Corbin based their saddle off of the shorter length '06 seat pan, not the longer '07-'10 seat pans. The connection point between the front and rear saddles are different and not interchangeable.
See this post
for the differences between the seat pans.
So this seat will only work with an '06 passenger seat. Even then, I'm not completely sure, as I've also heard that it only works with the Corbin passenger seat. Or that it works with the stock passenger seat, but there may be a noticeable gap between the seats. I've never tried a Corbin on the GT, so I can't be 100% positive, but it is something that should probably be looked into by anyone interested in the seat.
Sorry to be a bit difficult here, but I'd rather have a buyer that's happy instead of disappointed.

Some people see the gas tank as half empty. Some see it as half full. All I care is that I know where the next tankful is coming from...
