ok, one of my clients has a low rider its an 83. i pulled the carb for a rebuild and it has the preheater base. cant find the part any where. so i am just going to bypass the pre heater for now unless some one else can give me a better idea. also i was wondering if anyone has ever done a efi setup on a car like this one? put one on there so i dont have to keep rebuilding her carbs.
