I built the car today and everything was smooth. No issues anywhere. Ring gear cleared the chassis and I used white grease to help track the pinion and ring gear mesh. It was perfect. I did install a thin, very thin 16mm shim behind the inner bearing of the pinion to push the pinion towards the ring gear. It was pretty notchy and not at all needed. Dunno if anything was updated as it's the first Intech kit that I've built. Everything was perfect and was not short any bolts, had many assorted nuts and bolts left over for extra.
