Yes, they are the same except for the steer tube. They all had chrome AS bolts. 66's aren't as desirable because of the later style steer tube. The AS bolts on this one have clearly been robbed & replaced with later style cadium S bolts. I believe that this one is a 66 based on the tapered steer tube top nut and the bike having 66 style small cap bow pedals...parts possibly coming off of the same bike. It looks to have the later (smaller diameter) style stem (66+) and it appears to fit the steer tube correctly.
For those that don't know, the steer tube wall was thickened starting in 66 for safety reasons, resulting in the handlebar stem opening having a smaller diameter. This resulted in stems dated 66-up having a smaller diameter. 65 & earlier stems won't fit in a 66+ steer tube. The top nut changed from having a square top edge to having a tapered top edge. If the springer is pulled from the bike, a quick identifier is to look at the bottom of the steer tube shaft...if you see a ring of serrated vertical lines around the tube, then it is a 66 up steer tube (same as a krate). Earlier steer tubes don't have this...this is true for all Schwin Stingray head tubes on all styles of forks, not just springers.
