i got a 77 c10 that needs a new steering column and i was wondering what column are compatible and where could i get one
I'm pretty sure you can use one from '73 to '83, although I think there are some small differences. After '83 the wiper switch was moved to the column, but you can still use these if you want to rewire the switch there. You can probably find a decent one in a local salvage yard or find someone parting out a truck, if its a tilt it would be a good idea to rebuild it: check the bearings, turn signal switch, retighten all the bolts, etc.
The wiring of the steering column is also different, here are the years for the turnsignal switch wiring...hope this helps. 73-75...tilt 76...tilt 77-83...tilt 84-87...tilt Jesse Hazell Chevy Duty Tech. 73-74...w/o tilt 75...w/o tilt 76...w/o tilt 77-83...w/o tilt 84-87...w/o tilt
