The pedestal needs to be larger, especially front to rear, to resist forward motion under hard stops. If not you have a fairly long lever with the weight of the seat and your body pulling on the mount bolts whenever you stop. The harder the stop, the more stress.
John, the pictures in your album are amazing. Thanks for making them available.
