The money doesn't sound bad, but you need to be sure the unit is what you need for your 112. The 110's have a 8hp Kohler motor, while the 112's have 10hp Tecumseh motors. Each with their own mounting brackets. Also, if you're looking to keep the tractor as original as possible, the hyraulic lift handle shouldn't have any bends in it, and the original color was yellow. They used basically the same type of mounting bracket for the flat fender 112's, but the handle had a slight bend in it, and were commonly painted black. If there is a way of you showing us a picture of the unit before you buy it, I can tell you if it's the correct unit for your tractor. Does the seller also include a serial plate with the unit? Your tractor is origianlly a manual lift unit, and just because your putting a hydraulic lift unit on it, collectors will be able to tell by the serial plate, if your tractor is correct or not.
I'm only bringing these items up, due to being fussy about originallity. If you're going to be fussy enough, to only install original bolts marked as John Deere, then I figured you'll be just as fussy about the serial plate and correct hydraulic unit too. You will also have to find a hydraulic lift console as well, as tractors with originally equiped hydraulic units, didn't have holes where the manual lift handle mount was located.
Hope I helped, and please don't hesitate to ask questions, about anything else, before you spend money on something you may not be sure about. We are here to help!
