Not sure if I'm following your post-if you're saying that the newer releases of old kits don't have some of the parts, then I'm off target-if that's the case, same advice-Google search to find the instructions of the latest re-release.
If you're looking for input on the old AMT kits in general-
Most (if not all) of the AMT kits are kits that were released in the 60's & 70's-I remember seeing most of them on the shelves of my LHS.
Usually they could be build two or three ways-stock/racing/custom versions-leaving over parts for future use.
I've found that the best way to get an idea of what is in the kit is to do a Google search-I used the following search criteria: AMT 61 Ford Skyline
And found the following amongst the results:

Hope this helps=if not, sorry
