Rear Turn Signal Lenses

[Tortuga]

I want to install modified '59 Caddy lenses on my new to me '14 Nomad. I had done this on my '06 Nomad and '00 Venture. I had to cut down the length to fit the housing. Much to my surprise the '14 lenses are fused/glued to the innards of the light that hold the bulb. Anybody have any ides how they can be separated? Seems crazy that if you broke a lens you'd have to buy the whole guts and lens as a unit.
