Shortening steering column - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**FL71C10** · 06-03-2017, 05:24 PM

I just got a "new" 68 C10 and I want to shorten the steering column. It is a 4 speed truck, and I was wondering if anyone has ever done this with a 4 speed column. I read putter's thread in the Tech FAQ section, and am wondering how hard it will be to take the steering column out with the emergency brake handle and parts that are bolted to the column. Has anyone done this on a 67 or 68? Does a floor shift column have to have the slot moved like on an automatic column?

Any suggestions are welcome.

I don't think a 68 has an intermediate shaft. If it doesn't then take the steering wheel off it will give you more clearance toremove the column. You can collapse the shaft on the one piece design the same as an intermediate shaft.
For the locating slot, just drill a hole, 5/16 or so, that's what GM did on some van columns and it's much easier to do than cutting the slot

Thanks Firedemon. Do I need to worry about metal shavings getting into the column?

How hard is the intermediate shaft to separate from the main steering column?

Not bad as I recall, rag joint bolts and the one in the clamp. Wiggled it around some, cussed it a little, and it came out. I had the front wheels jacked up so I could turn the column to get to the nuts/bolts. Drilled the nylon pins & cooked it with a MAP torch til the goo ran out. Didn't have to beat it much. The thing I hadn't planned on is that the wheel gets CLOSER to the seat as it moves down toward the dash. Makes it tight to get my thigh between the seat and bottom of the wheel.

I'm a little worried about that too. I have an aftermarket wheel if it's too big.

The Impala wheel and the stock one are the same Dia. A tilt column would cure it, only takes $$$.

The floor shift column should be easier than the auto one, as you don't need to relocate the neutral safety switch up higher. I did an auto one and moved the switch. I telescoped the intermediate shaft using a hammer blow to shear the plastic pins. No heat.
I had a small diameter wheel which helped on the thigh clearance, but wanted a little more space, so went with a flat bottom wheel. I am getting used to that now! It is a little different..
I have a left over floor shift column that I didn't use, since I went with Ididit Rack and pinion length column witch is shorter than stock. I had to modify the instrument cluster to allow the bell on the column to fit into the panel a ways. Mine is a '67 with manual trans.
