Steering Column Length Adjustment

It's the last 5% of a project that's always the hardest to finish... I have a rebuilt GM tilt column, IROC box, stock upper dash yoke / bracket, and repop suframe. The mount holes in the steering column are about 3/8" from lining up; the column is a bit too long. I read a post about someone 'partially' collapsing their column to fix this. Any other non-BFH solutions?

Re: Steering Column Length Adjustment

No ideas on this? I'm at a loss.

If I pull the column back out and try to compress it a bit with a bar clamp, will I damage anything? Is there a shear pin?

What is the factory length, and where is it measured?

Re: Steering Column Length Adjustment

Bump...

I'm about to dig into this. Still no suggestions?

First, I think I'm going to try loosening the subframe and scooting it forward.

If I recall correctly, the 67 steering column is not collapsible, that was a 68 an up mandate.
Are the 3 steering column bracket support rods correctly installed?

Thanks,

Jeff

Re: Steering Column Length Adjustment

67 steering columns are collapsible, same as a 68. The shaft has a telescoping internal shaft section that probably has very thin plastic shear pins in it to hold the sections in place. Any hammering on the shaft itself will shear those pins quite easily. The outer housing has a collapsible area that is covered in plastic, just below the bracket. I'll look at my 67 and see if I can get you a dimension.

Re: Steering Column Length Adjustment

Thanks. I'm fairly certain the mount rods are installed correctly, but I'll double check them against my assembly manual before I dig further. It wouldn't surprise me, considering all the jerry-rigged crap I found in my car. It's so close, I'm pretty sure I can get enough movement out of the subframe. Just haven't had the time to try yet.

Re: Steering Column Length Adjustment

There are alignment holes in the subframe brackets that are supposed to line up with corresponding holes in the front body mount brackets. If those are lined up, you probably don't need to move the subframe.

The only reason someone would want insurance is if they want to pay someone elses bills or want someone else to pay their bills.

Re: Steering Column Length Adjustment

I'm working on mine this afternoon. Stripped out my heater and radio yesterday. I'll see if I can get a measurement from end of rag joint flange to the mounting bolts.

Re: Steering Column Length Adjustment

My measurements
First one is from firewall to rag joint flange. It's 5 1/4".
Second pic shows the steering column clamp at the firewall. Loosen this to slide it up or down.
Third pic shows the ruler butted against the upper side of the clamp, where you see the pinch bolt, measuring to the lowest bolt on the steering column 12 5/16". The column adapter bracket bolts to the column here. The camera is up against the trans tunnel near the shifter hole.
