VESCO5 - INNER PANEL MOUNT FOR VESCO3&4
Measurements, fitment, and other pictures...
Vesco bottom mount for seats
Since the Big butt seats are a lot wider than standard TZ seats, this bottom mount takes up the space between the frame and the seat. Makes installation a snap and looks super clean!
Designed for VESCO4, earlier seat without the lip. Needs some work to install with VESCO3 but can be done with some patience (and bondo).
