Nate,
The parts are well illustrated in the PC1988. There are two versions of the user's manual -- one for the belly pump version and another for the rear drive style. I presume that you have the belly drive, as that is much more common. I can e-mail you some information, let me know if you need another version.
The lower brackets mount below the hitch plate, whereas the "real" lower three point mounts are positioned above that hitch plate. the manuals show that both sets of brackets can be on the tractor at the same time. The seller is not well informed...
Here is a picture of the upper arms on the rockshaft and the lower brackets below the 3-pt mounts. The tiller specific parts are circled in red...
Here is a bit clearer view of that lower hitch plate area from the installation manual:
