How to easily distinguish FAV/WO E-parts tree?

[mongoose1983]

As title says, what is the easiest way to distinguish the original FAV E-parts tree from the modifyed Wild One E-parts tree?

When buying it is not easy to do so, nor to ask a seller that doesn't know anything about it. So is there anything in particular to ask for to make sure you're getting parts for the 1984 FAV?

The front arms on the original FAV are shorter than Wild One arms at the very end where the uprights / damper bracket fit onto . The re-re E parts are the same front arms for re-re FAV & Wild One
