Don't be discouraged, I bought minefour years ago and for the first 6 months sat there and wrung my hands "what am I going to do"
Don't make the car your frustration, make it a challenge in your Dads name to get it running to your standards and enjoy.
I now have 20,000 miles on it, and after not restoring it it but maintaining and fixing what has to be done, it has turned out to be a very reliable car. Don't over think it, join a Model A Club and seek out knowledgeable people from the club to help you with the items needing attention. When the guys come over to help, don't be cheap. offer them lunch a gift certificate from the tool store or Star Bucks'.
