Lockout Tube with a manual transmission

[GoMangoBoys]

We are converting our car from an automatic to a manual transmission.  We are rebuilding the steering column now.  What is the function of the lockout tube in a car with a manual transmission?   
Thanks

For  a reverse lock out, Controlled by linkage's. With it operational the transmission had to be in reverse to remove the key and lock the steering wheel.

Yup, 1970 only, gone by 71

Has anyone bypassed / disabled the reverse lockout feature with the 4 speed manual?  Having to put it in reverse to remove the key seems like a pain in the rear to me.

Everybody tosses the lock-out linkage even back in the day

How do I keep the lockout in the right place it the linkage is removed?

Mine stays put on it's own.

Typically you'll have no issue with it moving, and if it does, it's a simple fix while sitting behind the wheel....just turn the collar by hand until it's lined up again so you can remove the key...
