You're going to be just about out of luck getting a 60+ ring in 104bcd. You'll need an adaptor plate. I've seen 130 to 104 before, but can't remember where. although you can make one fairly easily. a 6" saw blade, a hole saw, a drill, and some patience is all you need to make an adaptor plate.
Whats youre rear count when you're at 112 cadance? if its a 13 on the rear, going to a 52 front wouuld drop you to 100, and going to a 52 front with 11 rear would give you 87
