I have not spilt open the transaxle, so I can't tell what side the ring gear is on. But I don't think it's a bus transaxle, since the gear housing part number starts with 113 (deluxe beetle?). It's also the same size and shape as my other beetle splitcase transaxles. I imagine the bus one is bigger.
Apparently, it came out of a European which may have better gear ratio's than the US version. I am thinking that down the road, if it has better gear ratio's, to swap the gear's into my 58 tranny.
Thanks.
