Before you spend a lot of money on just replacing parts on the pump, do a bench check to assess it's serviceability. Many of these old pumps are "leakers" meaning they leak gasoline into the engine oil and must be overhauled. Download the guides in the FI/Carb topic area.
Rather than spend a lot of money overhauling the injection pump and paying shipping to South America, you might want to consider a conversion to carburetors. If the expense isn't a factor, then fixing the Spica system is fine, considering that once in good shape, it is very reliable.
