The shifter housing bell, where the shift lever goes into, is different for automatics as well. You can still use that Deluxe steering wheel. There are two different variants that came out on some 64-66 C10 trucks. Can't see the front of yours but the Deluxe C10 steering wheel was also used in cars.
