Hang in there buddy. I got to your point and well beyond. That's why I have no desire for another project at this stage in my life. I'm enjoying my simple hobbies. Your car is more refined and will be less maintenence, I hope. I'm sure there will be plenty of days where you'll forget all the pain and enjoy the hell out of it. Remember, it's supposed to be fun.
You changed the oil, time to lay the pedal to the metal.
