I think they have. I seem to recall someone buying one new finding that it did. You may want to call AE as its possible the stock out there if you order online may be older than when they made the cut over. Heck, Ae has been pretty liberal about providing the shims, I know I just emailed them for the vheicles I had and they sent them out at the time, no need of proof of purchase, etc.
You may want to talk with Shark about the mods he has done for his lightweight SC10 4x4, it sounds like for your conditions could be the hot ticket. He also has done some interesting work on an sc10 4x2 conversion. With the price these go for used, could be a nice vehicle to have too and share parts for the classes.
