I have been looking at tilt steering columns for my '75 manual shift.   I see prices from $170 up to over a thousand dollars, and different lengths shown.

Bill, I believe the C3 T/T columns fall into 3 main groups not counting ‘68’s which were tele only, no tilt. The first group is 69-75 and that’s the group your looking for. They are getting harder to find and the prices are going up for a good one. Anything under $500 in good shape is probably a good deal. A 69-75 column should bolt right into your 75 and use the same steering wheel if you wish. 1976 t/t columns are a single year column that used the infamous “Vega” steering wheel. 77-82 T/T columns are very similar, a little shorter, have a smaller diameter wheel, but take some modifications to fit in an earlier car. They are more available and a bit cheaper, I don’t know if your 75 wheel will fit on a 77-82 column without some adaptation. A 77-82 column may also have hi/low beam, cruise and other functions you may not need or want. If you find a cheap column of any year that needs some work, most of the parts are available through the Corvette vendors. Hope this helps, good luck in your search for a good one. Also look for some input from a member named “persico “, I believe he just went through a similar conversion on his 70-72 car.

Hi. I am indeed going through a conversion on my 72 but unfortunately the project has stalled a bit due to the extremely cold weather in New Jersey. I hope to move the project to my basement soon! I bought a column from someone parting out a 72 that needs to be rebuilt for $500!! I’ll let you know how it goes. One thing you should do is look up Jim Shea’s steering papers online. He was the GM engineer who designed the system I believe. He even covers the specifics of adapting a later year column to an earlier application. Worth a read!

Thanks for your input.  I did find Jim's steering papers, and they are very helpful.  It looks like I can use 77-78 columns with little modifications in my '75.
