Quick note..
If you bought a Corbin seat and did not have an OEM top box...
no prob...
Then one day you get a wild hair... and find an OEM top box and buy it.
Word of advice... do not put it on your Tiger with the seat in place.
You need to shorten the seat about 1½". I just did that.
Peel back the cover at the rear of the seat all the way to the driver seat.
Using a side cutter w/ METAL cutting wheel, cut off about 1½" of length.
You need a meatal cutting wheel because the passenger backrest support
is built into the seat and it's metal..
I filled in with some new foam and glued it down.... no prob!!
