Now back to the turn signals, the ones on the truck are not stock Ford parts. Signals didn't come with the truck but you could order them as an accessory.
On my 49 I wanted turn signals but I didn't want to add an auxillary light anywhere. I took the stock parking lamp on the grille and pressed out the single element light socket and added a dual element light socket. The light sockets are readily available at any parts store.
