Robert,
My post count is not high enough to send a pm.
There's a plastic covering on one and not the other, I think it's just plastic but heat shrink is what I would replace with if I was using. The blinkers are plug and play, they still have the original butt connectors on each signal. My email is jterrusa2@gmail.com, if you're still interested reach me there and I will send you my PayPal.
