Where did these parts go?

[Michael Heidemann]

I fear that this will be a difficult task to find out because nowhere there is a tracker for parts renaming as long as the parts are not official.
I would try to identify the missing parts by substituting those numbers by another existing part, so you can see the location in the model. With a look into the building instructions and the inventory (http://www.peeron.com/inv/sets/8070-1) it should be possible to find out which parts you are searching.

Just an idea to solve your problem.
