What a difference an inch makes.

my fault, I didn't realize you were the seat track spacer police. that's nice that you would assume responsibly if something were to happen. good looking out !
I have to back dave up on this one,from zero leverage on the bolt to 1-1/2” height added. May be fine but in the event of a rear collision there would be a failure there.
When i build pedestals or raise them, i keep this in mind.
