1960 Apache 10.
Question 1. I have the clear lenses so I’ll buy amber bulbs. But I’ve seen 60s with amber lenses too. Did Chevy change to amber mid year?
2. The bulb housing grounds to the hood, correct? I have no continuity between my hood and the rest of my truck. My hood is firmly attached and I don’t think I can attach it any betterer than it is now. So I plan to connect both bulb housings to their own ground wires and run it down with the other lamp wires to the body itself. Anyone else done this?
3. The bulbs are so loose in the sockets that the bulb only illuminates if I press it quite firmly into the socket. Is there a trick to tighten these up? LMC sells replacement sockets for $3 but I’ve heard of replacement sockets being crappy from the git go. So if I could make the old ones work I’d rather do that.

I realize my truck was built almost 65 years ago but this turn signal grounding system is a pretty optimistic design on chevy’s part. Opinions?
Thanks!
