we just put a tilt column from a 82 automatic in a 77 manual
we had to change out the shaft all the way to the rag joint.
the shaft was different in how it attaches to the column but if you get the entire shaft it will bolt up to your old rag joint.
we just knocked out the pin and removed the automatic shift lever from the collar
Im sure someone sells a manual collar, but we didnt want to pay for it and spend the time swapping it, and no one is gonna notice anyway.
the wiring harness plugs for the turn signals are the same, but the other wiring plugs are reversed, you just twist the dash wire and plug it in backwards. the switch on the older one is a pusher, and the newer ones are a puller, so GM just flipped the switch, bolting the bracket on the opposite side.
your milage may vary, I know the donor was a 82, but our truck is a mutt, a mish mash of several different years.
