Re: 67 Telescopic column
Thanks for the reply John. I am going to start a new thread about the spring tension on the telescoping steering. (see post and picture above)DaleComment

Re: 67 Telescopic column
I reviewed my column closer based on the info you all provided. I have no date information of any kind in the location Jim indicated on the column. The plastic spacer can clearly slide up as well. I also noticed the length of the plastic spacer is longer than the one shown in one of the photos posted. I have included a photo with a scale to show the length from the end of the column to the start of the splines.Comment

Re: 67 Telescopic column
Hi Dereck,
All the 1967 columns pictured are of the 2nd design. I believe you stated that your 67 had a Sept. 1966 build date. This car would use the 1st design column which uses a snap ring rather than the clamp on the lower part of the shaft. Expect a deduction for a 2nd design column in a Sept 1966 car.

Re: 67 Telescopic column
Dereck,
With respect to your latest picture. Your steering column is not assembled correctly into your '67. The firewall clamp is squeezing on the mesh section of the steering column. You should be able to find two sets of "thumb bumps" stamped into the metal section of the steering column. The firewall clamp should be located in between the thumb bumps. The column should be further up into the interior by about 2 inches.

Re: 67 Telescopic column
Jim,
Great observation that I never noticed. Attached is another photo showing the underside of the dash. The location of the slots also suggests that the column should move towards the driver more. I assume that if I unlock the telescopic lever by the horn button and extend the wheel towards the driver that I'll be able to slide the entire column towards the inside of the car once loosened. The column would have to move relative to the shaft. This should lengthen the area next to the coupler and make it look more like other columns I've seen. Another indication that this was added to the car during it's life. I'll give it a try.
thanks,

Re: 67 Telescopic column
Dereck,
From your picture you can see that loosening those three bolts that attach the aluminum capsules to the dash structure will only allow the steering column to slide up into the driver compartment by about one inch at most. From my last posting I figured that the column needed to move at least two inches.
You can see from this scan that the three bolts (8) screw into plate (3). Plate (3) is held against brake support bracket (2) with four bolts (4). If you loosen those four bolts you should be able to slide plate (3) forward by some amount. I hope that this will be enough to position your steering column with the column clamp (1) positioned between the thumb bumps.
If this isn't sufficient then some major distortion has occurred in the body and birdcage itself.

Re: 67 Telescopic column
Jim , my February 6 BB car has a C 31 7 stamping on the column . What is the date of this column ? Also, my spring looks a whole lot smaller than Dereck's spring , is my spring incorrect ? How hard is it to restore the column , replacing the bearings and for me I need to straighten the cage surrounding the steering shaft? thanks DelComment

Re: 67 Telescopic column
Del,
The date coding is not in the same order as the assembly drawing would indicate. But I would think that 31 stands for January 31. The C means that the column was assembled on the C shift. 7 would indicate 1967.
Awfully close to your Corvette build date. However, with the GM Corporation and Saginaw Steering Gear in the midst of a steering column campaign it is possible that assembly plants were literally working had to mouth with Saginaw.
I just don't know about the difference in springs. The spring on Dereck's column seems to be too heavy to just preload the lower bearing. (Particularly if it is supposed to be compressed nearly solid.) If I had to guess, I would select your spring as being correct.
Make sure that you check your steering shaft to determine that it is straight.

Re: 67 Telescopic column
Jim , I took a plastic headed hammer and gave the housing a wack and it straightened ...now the shaft spins freely .
Is the 5.25 " mentioned in the thread a distance from the end of the shaft to the bearing housing ?
Could you also tell me where the white plastic piece around the shaft be located. I did look at your paper but couldnt find the white plastic piece. If I downlaoded and printed your paper would the diagram be clear enough to read ? thanksComment

Re: 67 Telescopic column
That 5.25 inches is from the face of the lower bearing retainer to the beginning of the serrations. It would be 7.32 from the bearing retainer face to the very end of the steering shaft.
Those diagrams in the paper(s) will become sharper if you print them out.
I was never able to obtain the original 1967 Telescoping Steering Column drawing so the original parts and the campaign added parts to that original column are a mystery. I don't have any information on a white plastic part.

Re: 67 Telescopic column
Jim , just to clarify , the 5.25" is for a standard steering column and telescopic column . thanksComment

Re: 67 Telescopic column
It is for the 1967 telescoping column.

Re: 67 Telescopic column
Jim,
I can't get the column to position correctly inside the car as I try to slide the column further in the interior. Any way I have a corvair tele column? I've seen one of those at a swap meet and it appears very similar to a 67 Vette. If so, is the Corvair column a different length? My column doesn't seem right somehow.
