We have always known as the lock pin. This pin was the same in every Saganaw column I have ever had apart with tilt, without telescoping column, with out air bag. Best source I can think of is have a dealer check for old stock. Nally Gm seems to have a decent stock for a current dealer. Use their parts look up to get the number. Use another car as a starter to look up. Something more popular. RWD Malibu? (checked the same number as Malibu and Nally is showing a price normally means they have one.)
Had both my wife's 2001 Lumina and mine apart last year. Besides the different lenth. The only differences were the Wiper switch cover, Larger wiring hole for the air bag/Vats, The lower shell, on the tree shifter. and the lenth of the shell behind the steering wheel. A little deeper and would expect the top shaft and locking pin were also longer to make up the distance. Every thing else from the steel tube up could have been installed in my column. Also look for people chucking them. Many just get another column when the lower bolts come loose or sheer off the main tube. What a waste. Might be possible to use one of the later ones with airbag but you would have to check the lenth. I don't think they changed the diameter of the pin. (checked that, yea different number, but were some same numbers)
Odd this is one of those parts that didn't seem ever to have to replace unless the car was stolen a few times. And someone "tried" to break the locking ring causing a ridge/bend on the pin that would keep it from locking. Several insurance redoes over that one. Until the thieves got smart enough to break the plastic wiper switch cover and just pop off the plastic rack gear.
