Is the height of the keylock boss on the 69 steering column *different* for the non tilt column vs the Tilt column?   My car came with a non-tiltcolumn, but the space between seatback and steering wheel has shrunk significantly since I last drove it in 1980 ... Smiley , so I'm considering installing a tilt column.   In comparing the original non-tilt and restored tilt columns, I found a couple of differences:

Height of Keylock boss
Attached are photos of the boss for the keylock cylinder on the two columns:
Non-tilt column, followed by the higher boss on the Tilt column:

Additionally, the paint color on the bottom of the steering column is different:
Attached are the bottom showing the difference for the Non-tilt (green paint), and tilt (restored black)..

Is it 'normal' that the height of the keylock boss on a tilt column is so much higher than a non tilt?
Is the 'green' painted end of my original non-tilt factory correct?  Is the TILT end different and is the 'black painted' also correct?
Any/all help appreciated. 
I need to know if this tilt column is correct re the keylock boss height and original type, and if it is, do I need to paint the end green to match the original column before installation.

Steering columns were received from Saginaw in black primer, and the top 12" or so was painted interior trim color in the car assembly plant.

At '69 start of production, we were supposed to use a felt pad with white ink (paint) on it to highlight the "LOCK" lettering cast into the column adjacent to the ignition key boss; this process was really flaky and the results looked like it was done by a five-year-old, and shortly that highlighting requirement was cancelled.

John,  thanks for your comments!   

Re the 'green part' of my original column.  Do you think that is where the saginaw applied black paint didn't adhere well?  That column has never been out of the car, but when I saw the green showing thru the black paint, I cleaned off the black (which was very easy to do);  I believed the spotty black that was on it was from my 'spray bombing' it black in the mid 70's which was at least partially true..

Gary is that green piece hard plastic? I think mine was the same way yours is. I looked but I can't find my pictures of the steering column.  Oh and that key boss don't look right but I could be wrong. It seems that's a later model thing if I remember correctly.

Tmodel:   It could be plastic, it does have that look, but I didn't even consider that possibility.   I'll go check it with a magnet .. Smiley

I've taken another look, and tried to use a magnet on it, but that's difficult to do with so much metal so close to it.   I do tend to think it might be plastic due to it's shiny look.  Perhaps it was a stop/spacer used in the factory when they installed the coupler to the end of the shaft?

Oh and that key boss don't look right but I could be wrong. It seems that's a later model thing if I remember correctly.   
Are you referring to the taller key boss?  on the tilt column?   I have both the restored tilt column, just purchased as 'original restored' from Gary's classics in Athens, TX.. and I also have an original tilt column of the late sixties era, both have the tall boss for the keylock, but my samples are limited, which is why I asked the question hoping someone with a known original tilt column in their 69 Camaro can respond...

Gary I just looked in the Service Manual and the green piece shows up as a spacer and I still think it's hard plastic. The tall boss would be correct after refreshing my memory because the tilt has to relocate everything.

Mine is a 4th week Jan 69 Van Nuys car w/tilt (column assumed original I,ve had it since 82)
High key boss, no green or black "spacer" I only see the splined shaft where this piece would be ?

Thanks for the followups (Azure and Tmodel).  I think I've gotten enough confirmation that I can proceed with reasonable confidence that it's *right*... Smiley
