I just put on one of those 10x1110's yesterday.1100 vs 1110 is only a 10mm
difference-- not even a 1% variance. The alternator has plenty of
adjustability, so it's fine.The important part is that it's not so long that
you won't be able to take up the slack when it stretches a bit.
My alternator is a Bosch AL27X--replacement

They're both 90amp alternators, but the AL27X is the direct replacement, the
one that's preferrable. I'm not clear on the difference, but as I understand
it the AL33X requires a little fiddling to work. Just wiring, I think. I bet
Ken at Vanagain knows.
Lastly, I assume I have to remove both the power

Pull that little hose off the bleeder ring side rather than trying to reach
the hose clamp on the head side. Plug the hose with a small bolt or allen
wrench or whatever, so when you forget and let it drop down it doesn't
dribble coolant into your shoe, like it did to me. Other than that, it's
just a matter of fiddling the belts into place and tightening 'em up. While
you've got the alternator/water pump belt off is a good time to grab a
flashlight and eyeball the .9bar oilpressure sensor connection. It's right
there under and between the crank pulley and water pump pulley. Make sure
it's seated all the way and the wire looks OK. When you're taking the old
belt off, be aware of the connector and don't knock it loose-- it's a tight
fit down there. I'd wager that many an oil pressure buzzer has gone off
because some greasy tire-changer at the local garage has done just that
while changing belts and didn't know enough to check once the belt was off.
