Raised seat in front 1 3/4 inches which left big gap.  
1-Took rubber bumpers off front of seat.
2-Screwed them into the holes on the frame after a little resizing on sander.  
3-Pulled rear bumpers to stretch rubber then put in 2 thick nylon washers.  
4-Got some discarded IKEA furniture bolts and red locktited a nut on each.  Then rounded them on sander.  I always carry a fold up allen wrench set in my pocket so can finger tighten bolts then a little extra with the wrench.  
Easy to get out since they protrude past the edges of seat and up above rear light.  All this in the pics.
