I bought my two tone GT5 front lenses from Larry LF-TP2511 on this board.
Yes, I still have them for sale. However, I sell complete sets - housings and lenses. David is just seeking replacement lenses.
He and I exchanged emails some months back. Original lenses are found on occasion in Europe eBay listings; David, as did I, found them to be very pricey.
Stock Ford front signals came in amber. They were also in clear, in Europe. This style had the holes in the middle on opposite sides. Both colors will interchange to the same housings.
The GT5 front lights came in amber/clear. This style does NOT interchange with the Ford style; mounting holes are in opposite corners. To upgrade to this two-color style, you need housings and lenses. Clear lens becomes a 5 watt running light, the amber is a 21 watt signal light. These are the same wattages, and function, as the stock two-filament bulb.
