I think all the box's manufactured from August 92 to August 96 will have the asymmetrical dog teeth on 2nd gear Frank but they also changed the outer ring and synchro rings so between them they probably account for the stiff 2nd gear on yours compared to mine. Be interesting to hear if anyone has a box from between those dates (manufacture dates not registration) that doesn't have a stiff 2nd gear and also what they were like before August 92.
