The reason why the stereo is like that is because the owner removed the cheap head unit adapter lol I will be replacing that anyway. My friend who helped work on the car said they changed all of the fluids a few months ago and drove it for 2-3hrs and it is solid. I also know a mechanic who will be replacing the head gasket and such, which seals and gaskets should I replace while getting the head gasket changed? It's a 20 year old so replacing some of that stuff would be a good idea while the motor is being worked on anyway.
