Pete, I would seriously think about using wider driveshaft from start. Actualy I'm looking on other Toyota to find a donnor which would have driveshaft about 4 cm longer than starlet
About driver side. i have found corolla ee111 drive shaft which are approx 2 inch (5 cm) longer than our stander shaft.
now I'm looking for a passenger side 2inch longer shaft. it sounds to be the tuff part of the game. any idea ?
