Lots of info about the Model A Ford and in particular the 68C body style.
The Model A is an interesting car. It is a transistional car built by Henry Ford, or rather designed and built by a lot of smart engineers based on Henry's ideas. Ford at this point truely thought the Model T was the only car you should ever need. Then sales really slumped and Henry finally decided he needed a new car.
So the Model A was designed to be a car that was low cost and durable. While many today do not believe this, the car was built and advertised to run 60 MPH on the crappy roads of the day. The car also had to be easy to keep and get good fuel mileage. When new the car was known to be extremely reliable with exception to tires, batteries, condensors. They really did not know the science to make batteries, condensers and tires like we know today so they tended to fail often.
Yes, the cars were driven 60 MPH all the time. If you take the time to learn the history of the A the speed trials were a common thing with the maturing auto market. There are many stories of the cars being driven cross country or just around the county. The car was run hard and put away wet and it just kept going.
It was designed so well that it would still drive even with most of the parts well beyond their wear points. So you can take a pile of worn parts and likely build a car that will run around town. Just do not expect it to stop well and handle nice over 25 MPH. Oh those people that say their cars only are good to 45, well something is usually not very right on the cars. Most I have seen I feel are unsafe over 25 MPH.
Over the years I have learned a proper mechanical restoration requires knowing factory specs on the parts (no I am not talking Judging Standards). I have seen many factory prints. For those who think the car was just a cheap car thrown together, they have it very wrong. It was precision built and rebuilding the car is like building a race car. You have to be able to work to .001" accuracy for some areas. It was truely eye opening as I started the restorations of the various mechanical areas of the car. To be honest, at first I was measuring the parts wrong. I was not using accurate enough measuring devices or not operating the instruments properly.
If you are restoring a car be prepared for an interesting journey. Becareful of word of mouth advice, always double check the facts. Do not trust any books as the final word, they all have errors. That being said, if I have something wrong please inform me of the error. If it is technical, then be advised I may request proof. I like to verify my information.
