Does anyone know if anyone reproduces the round guide power beam headlight bulbs gm used in 75? Im trying to keep my car all original and really dont want a modern sylvania silverstar logo on my bulbs. I see someone on ebay selling complete sets of 4 for around 170 bucks plus 20 shipping but theres the fear they will burn out the first time i light them in the back of my mind. I thought about maybe switching to the t 3 reproduction bulbs but i think they were discontinued by the time my car was produced in september 74.
P.s. thanks to everyone putting up with all my silly questions, im a ford guy and gms are an entire new world.
