f5fstop or anyone else is this safe

Well my OCD kicked in Saturday and I fabricated a couple of brackets to raise the driver?s seat one inch. I made the front brackets out of ?? x 1? flat steel, and the back I just used flat washers to shim it up one inch. Works great except for hitting my head getting in and out. But, Is it safe? I noticed there were a couple of metal pins approximately 8mm in diameter that went into corresponding holes in the floor board when the seat is mounted flat on the floor board. When I raised the seat up the pins were not long enough to go in the corresponding holes. Is it safe to drive it with out the pins in their holes?
