I've seen this question asked a bunch, But I don't think I have ever seen a real answer. I have heard of people swapping in a Telescopic column from a Caddy or some other luxury Car. My 78 K10 was the worse, the 86 C20 and My 85 K1500 don't seem to be that bad. It's probably just me. I don't think there was a difference in length.
I'm looking for an answer myself.
