Review on Standard Motor Products S49 Pigtail/Socket Assorted - Affordable and Convenient Solution for All Your Electrical Needs! by Kevin Griffin

They appear to be of good quality and fit a 1967 GTO. I had a little trouble trying to install the 1st. The size is right and the plastic fingers are a bit longer than the original, which I think is a good thing. The two metal protrusions on each side of the connector appear to be an issue when inserting into the plastic case. I took a pair of needle nose pliers and squeezed them a little. It helped a lot to install them. I didn't want to put too much pressure on the 55-year-old plastic. Before connecting, it is better to install a socket and a light bulb.
