'68 fender mount turn signal question

I have a pair of '68 bullets that I'd like to have rechromed. How do you disassemble the guts ?
FWIW- these have a smooth lense and not the one with the typical slot in them.

There is a tiny allen set screw on the bottom of the bullet that you loosen. After that the guts will come out but you will have to dike the wire to get that all the way out.

Got it, thanks.
