As far as I know..
There isn't any place that can make "one off" custom tail lamps.
Make the inner frame out of sheet metal, make a wood "buck" for the lense shapes.
Place a piece of red plexiglass on the buck, place in the oven at around 250 degrees.
Heat until the plexi starts to sag, then once it settles onto the buck, take it out of the oven and wait for it to cool down.
