Mt brake lights are staying on in my 1976 Series 75. I need a brake light switch retaining clip. Googled it and came up with nothing specific to Cadillac but a whole bunch of them for 70 to 81 Chevy's. The photo looks like the one in my car. It's only 8 bucks. You think it's the same part ? I'm thinking this because I also have a Mark III and 75% of that car's parts are the same as a T Bird.
