Hello hope all are well. I need help advise with my 1968 front turn signals. They appear to be original and have a parking light or marker light and a turn signal total of two bulbs. My housings are pretty shot and the bulb sockets are temperamental. My question is will new housings with the single bulb plug and play or will I have to do some rewiring to the harness. I tried to search this topic but not getting any luck. Thank you any and all help is appreciated. Oh I haven't bought new housings because im not sure whats going on.
