Except maybe I can’t. I’ve no experience swapping flywheels in these older trucks. A 10” clutch disc will work just fine with a 235 engine. I know the 1960-66 trucks had mostly 168 tooth flywheels but not all will accommodate an 11” clutch disc. I took this picture to help you see the differences at a glance. Both flywheels are 168 tooth.
If you have nothing better to do, come sort through the pile of flywheels at a local salvage yard 40 minutes west of Columbia, SC. Haha!
