hmmm, I wonder something. Here I found a gear box set for the rear, it says 2.0 buggy/truggy, but it says it also replaces the original (losa4428) gear box. BUT, this set comes WITH the bearing inserts you guys were talking about. Would the ones in this set be plastic or would they be the aluminum ones?
