Yes, they came with low pressure 235's. Only the engine ID on the raised pad next to the distributor can tell us if it has been changed. The axle my be original with an adapter, but it has likely been changed out with a modern one. The rear rims don't look like splits, but the fronts are.
Email me at david(dot)colter(at)sbcglobal(dot)net and we can both crawl all over the thing soon. We'll get it for $500 or less.
