| I just changed out of a OS71 to a YS91 and I got the 8.18 gear, (where I wished that I would have got the 8:45). You will need a lower gearing ratio of 9.3:1, this means that you have to change the side plates (because the hole alignment is different), get different motor mounts, and change your 11 tooth pinion for a 10 tooth. Everything else will work (i.e. 93 tooth main gear).
I have all these parts, if you would like to trade with me for your 8.45 stuff, I'd be willing to send it to you. I'll post pics if you want me to.
