This brings back good memories from 1997 when I was the first in Norway to convert a car to an EV.
I spent about 200 hours on this conversion, and it was not really that hard. I got my parts from http://www.evamerica.com/ and made a deal with my wife to work in the garage every Monday after work. My old website from Geocities have some interesting pictures, particular on the clutchless design of connecting the original transmission to the electric motor. If your are thinking of making a conversion I would suggest you to check this out: How I converted a car to electric . It also have my log of the joy of driving an electric.
