Manual Steering Shaft

Hey yellow1, I'm no expert on these steering shafts...... I restore cars for a living and I've seen many different things on cars, anyway it is highly possible that there is a big difference between the 69-70 model cars, as for like Dave is saying in 69 the key is in the dash, and in 70 it's in the steering column..... so big possibility it is different, But I'm not sure, as I have never had a 70 and newer column apart before as most of everything I work on is 69 and older type vehicles. As for drilling a hole in the column..... It would have to be exactly as original, I'm not saying it CANNOT be done but I would be very careful. I'm not you, but I would not attempt it myself. I would continue to look forward for the exact piece you need!! Just my 2 cents!
