Based on the rear springs, it appears to be a 42-46 two-ton. Sweet! Not sure on the rear end, but whatever it is, you can figure on 45-50 top speed, as these old gals are from an era before the national highway system existed and likely geared 6.17. Great for pulling hills & stumps but not much on the top end. Take a look at the GM Heritage Center site below for full documentation. Welcome to the 'Bolt and have fun with the re-build.
