I know what you are saying about the "wonky" id system. I even contacted specialized and they pretty much told me the same thing you did about 4 days ago now. All the other 82' serial numbers though are much higher with not as many 0's. But i did research it , they have a chart of all the different years and the different parts.
it has the AR front and rear Suntour Derailuers i believe it is, but it says AR, and it has the specialized headset not the channel seal headset listed for 83'.
The araya rims with the suzue sealed lugged hubs only listed for 82'.
Only one other year had the araya rims and it was the 83', and the 83' had specialized sealed hubs, not suzue, also the 83' had suntour Mountech deraileurs, Not suntour AR deraileurs which i have on my bike.
My bike also has the TA Specialties cranks made in france, as for the 83' it says it came with Sugino at triple cranks
My bars are not labeled i dont believe, but they are an alloy raised bar.
And for my pedals, they are not suntour pedals, they are bmx style.
heres the specs
