Well if you haven't heard T/C has the 2 over kit ready for 2nd Gen Tacoma's now. They just had to finish the axles and had a couple trucks testing it. The FJ has different spline axles I guess so they never offered it. They suggest fiberglass, but the pics I was sent was 33's with trimmed stock fenders. 11.5" of travel. Seems like a good alternative to All-Pro.
Not gonna post their pics I was sent cause they aren't mine, but if you go on http://www.chaosfab.com/86002.php the have a couple on the FJ section and should update soon. They guy on their has RCV axles on his truck...$$$.
