I actually "made" the missing teeth with high strength 2 part epoxy. This
was just strong enough to get the car to pass the safety inspection which it
did. I think there were only about 2 missing teeth iirc. I never drive in
the rain so this worked. I eventually bought a used wiper motor assembly.
Fiats of that vintage seem to have an endless array of different wiper
motors. The good news is that by swapping the wiring harness and crank arm
from the old one, they are mostly interchangable. Some Yugo GV motors (the
ones that LOOK like a fiat motor- apparently they had two different
vendors.) will also interchange.
The important thing is to lubricate the wiper spindles so that the new one
doesn't eat its gear as well. Fiat used a combination of brass and steel on
many of these which will get really tight if allowed to sit unused. This can
be a real problem on "fair-weather" Spiders!
If you don't have any luck locating one locally (where are you?), drop me an
e-mail. I have got a couple of left-over Spider motors that would probably
'78 124 Spider
'71 850 Spider
'87 Yugo GV
'94 BMW 740iL (what was I thinking???)
