Would you mind telling what spindles you used on the front axle of your tractor? Did you use a pinto rack? And did you buy or build your coupler to the transmission??
We used the front end off a John Deere 55 combine, heated parts to make them fit, and then made a couple other adjustments. Also, we had Aulick's in Scottsbluff make the driveshaft that couples the automatic transmission to the tractor rear-end.
