Tires wearing on outside

[vince1]

I took out a .115" shim out of each of the four positions and lengthened both turn barrels 1/4 turn, then took it for a ride down the road and hands off it goes nice and straight. Sighting the wheels to the back they no longer have so much toe in. The differential was changed out to the wider 71 model some years ago but I don't know how much if any the width differs from the fronts.
