Sorry for the slow response. I'm with Mark, I don't like the electric pump conversion. The original pumps are not that hard. If the original pump is still turning now, it will likely keep turning. I last redid mine in 1998 or so and it's still fine and not leaking. If the gear teeth are broken it's because somebody serviced it incorrectly; they don't just break for no reason.
The parts and procedure are all available at:
I have the VSCNA tool collection and can lend you the tools if you need them. You will need an intake manifold gasket and you'll probably have to make a water pump cover gasket.
2 bits of advice:
1) keep the original water pump shaft. It's been happy all these years with the engine "jackshaft", don't tempt fate by changing it! (this has led to a lot of gear tooth failures).
2) set the impeller to cover clearance carefully! The website shows a good method (the grease) of checking it. I prefer to tighten the impeller all the way down to the shoulder on the shaft and then set the clearance by using a thinner gasket if needed.
Contact me if you need more info - I also have the "final" Saab Service Bulletin on the procedure.
