cruise control

I've got a '75 Delta 88 Royale Convertible and the cruise control regulator is shot. Is there anyone out there rebuilding these anymore? I'm assuming they're the same all on GM cars from the era. Or, anyone have a good one to sell that's been tested? Much Appreciated! Corey

I have a 2000 Olds Intrigue that continually shuts off the cruise control after a short period of time. The light goes off on the dash and the cruise disengages. The dash buttons seem to be working if I turn the cruise off before it malfunctions. I have to turn the car off before I can reset...
