Hinge-Upgrade for Vespa Smallframe

The initial seats produced from early to mid-2014 lacked fixed press-fit threaded bolts installed in the rivet plate beneath the seating surface. Additionally, the arrangement of the spacer sleeves differed. Consequently, the hinges are only compatible with the new rivet plate featuring press-fit threaded bolts. It's advisable to confirm the type of seat or version before proceeding.

Instruction:: Remove the bumpers, screws, and cover plate. Then, verify if the spacer sleeves can be loosened to reveal a press-fit threaded bolt underneath (versions 2.0 and 3.0). V1.0 is equipeed with standard M6 bolts.
With version 1.0, large washers are still installed underneath the spacer sleeves.
