Nope. Cant be done. Send your differential to me, and I’ll send you back an iBrick.
Helps if you give some detail.
That cart?
Iirc, 12.44 was stock on those.
Pull the fan shroud off the motor, jack the cart up, block one wheel, mark 12 o clock on the free wheel and the fan, start trurnubg the fan slowly by hand and count revolutions until the tire makes one full rev.
Then take the diff out and mail it to assyreqd Then I’ll still send you an iBrick
