Steering column compatibility?

[sethv]

Hey guys. A good friend of mine has a 1981 Chevy K10 with tilt steering and the column is bad and needs replaced. I can get her a column out of a 70's truck but I was wondering if there were any major wiring differences between 70s and 80s trucks?

Rebuilding the tilt column isn't an option, she just wants a different one (And the one I can get is not tilt so we won't have to worry about it breaking lol)

Thanks guys.
