67-72 Steering Shaft All The Same??

[cwilkie]

Is the steering shaft that connects the column to the steering gear box the same for all 67-72? Is the new one in LMC any good? The one on my 1968 rattles every time I hit a bump. I was in the junk yard last week and I noticed the column on a 1970 had a different looking steering shaft from the one on my 1968. If that is the case is the 1968, 1970, or LMC shaft more reliable? Thanks!
