Does anyone know of someone that can recondition headlights? Re-chrome the reflector and stuff?

what headlights mick? it would most likely cheaper to buy new ones.

5 3/4 cibie's for a concourse car

 do you have a  pic of them

I am pretty sure you can still buy the reflectors for all the old Cibies.
5 and 3/4 inch is standard Oscar and you can certainly get them.
Try Demon Tweeks, Rally Design etc, heaps of advertisers in the UK magazines, basically anyone that supplies Cibies will be able to order them for you.
 
Last time I priced them they were about $80 each here in Aus through Revolution but at the time a pair of new lights was only about $220 all up (couple of years ago now), so I just keep my eye out at swap meets and buy them whenever I can.
 
Cheers
