(Commuta_Busa @ Apr. 25 2007,07:03) The cheapest way... is to dremel the flap off, then take a soldering iron to smooth out the whole edge. Goto pepboys/R&S strouss/wallmart and pickup a trailer hitch connector. Splice it into your tail light wires and you'll have the two brake light bulbs intigrated as turn signals.
Total cost in parts maybe 10 bucks.....
