The tips already provided by others regarding using either table top or two saw horses to support the stab at close to the correct height and then adjust as needed are valuable.
If a table is being used, you can use a stack of the aviation magazines that you probably have sitting around as spacers to adjust the height.
You can even use the nose wheel tire pressure for very fine adjustments in tail height.
I have removed/replace the stabilitor on numerous RV-12's numerous times entirely solo. It is not that big of a deal.
BTW, the reason washers are in that difficult to install them place is to provide opportunity for some dimensional adjustment because of tolerance variation, etc. If the normal washers don't work, they can be sanded down thinner of make some from material of a different thickness.
