I'm installing a new wire harness in my '56 Country Sedan and am stumped on how to remove the front turn signal housings. I have the three bolts on the bottom removed and the units are loose but there is still one (?) bolt holding them in place near the outside of the housings. If I can't figure out how to remove something so obvious, I probably shouldn't be rewiring the entire car. But we're committed now, there's no going back.
