engine has power steering and pulleys for a/c but I do not know if it had a/c. the tractor has a home made wide front axle that uses the Buick wheels and spindles, as well at the Buick power steering unit. even has the speedo cut from the car dash mounted and hooked up showing 73k mi. from the bent rims etc, I am guessing the car was wrecked around 30 yrs ago uses turn signal lever for auto shifter and Buick radiator mounted sideways in front of Farmall rad for extra cooling routed thru a home made heat ex-changer and 2 coolers for the super turbine 400
