Anyone here have a 1975 or newer A body with N88 Speed Control / cruise control?

Don't you worry! I've taken quite a few complete cruise control systems out, I get every nut, bolt, wire, stop light switch, turn signal stalk, cables. I have several NOS stop light switches. I bought a big box of NOS cruise control stuff from a dealer that had closed down and had an auction. I have 3 complete A Body setups.
Lemondana - the bracket pictured is correct for an A body cruise setup. Unfortunately, you would need the entire setup to make it work. This means you'll need the turn signal stalk, all the wiring including the brake switch, the servo/cable/servo bracket, and most importantly the carb linkage which is a bunch of little parts that are specific to a slant six carb. The left inner fender on a 1974 A body IS NOT dimpled to accept the three holes needed for the servo mounting bracket, by the way. But yeah, it will work on a 74 A body if correctly installed.
