Seat doesn't latch out of the box so i removed both stock seat brackets from rear fender. The bracket for the tool case and the front bracket for the passenger pillon.
It looks like i need to bend the rear tail bracket and add shims to the bottom of the front bracket that snaps into the seat latch.
For trouble shooting i removed the front metal bracket and tried to latch it without the seat and it's still very tight.
Would appreciate any suggestions and solutions from someone that has hands on experience with '04' Stinger with similar problem.
Enclosing jpegs of parts discussed. Would have called Corbin but received seat late Friday!
