Hey,Mike, Since it's in a 1ton truck,I'm gonna assume it's a 4spd tranny on the floor. What you need to look for is any 67 to 79 half/3/4 or ton with the 4spd tranny. Assuming(again) you have Power Steering,you can get one from any junker with PS,4spd. If your truck doesn't have power steering,you can buy steering box,column and all,and switch it to power steering.Good luck with it.
BTW...check to make sure it's a good column before swapping it!
