Shim for 1970 steering column

Has anyone used a shim or wedge to center the steering column in the dash opening of a 1970 Chevelle SS? What do they look like? I see shims/wedges listed for sale for 1967 Chevelle steering column on various sites, but nothing for a 1970 Chevelle.

Re: Shim for 1970 steering column

I've never seen or used one. Perhaps your bracket is installed the wrong way?

Re: Shim for 1970 steering column

I don't know how you could do that with a 70 column to dash mount.

Re: Shim for 1970 steering column

I would think the plastic dashboard might be a little off center left or right rather than needing a steering column shim.

Re: Shim for 1970 steering column

How far off center is the column?
Picture?

Like Rick said above, it is possible that the dash is skewed. Is the center bolt above the steering column that holds the dash in place? It "centers" the dash somewhat.

I am reading the new book Chevelle Restoration and Authenticity Guide 1970-1972 which discusses steering column removal on on page 171. It states occasionally you will encounter shims for the steering column and to record how they were installed so you reinstall correctly or the column won’t be centered. My column is somewhat off center, which is what led me to conclude shims might correct the problem. I see no evidence the car was ever wrecked. By the way, the book is excellent.

I didn’t think about the dash being skewed. I will check the bolt you mentioned and see if the dash adjusts. It is off slightly to the left. I attached a picture. Thanks for the excellent suggestion.

Re: Shim for 1970 steering column

Dave, I just googled 70 dash pictures. None appear to be centered.

Re: Shim for 1970 steering column

If you loosen the 2 bolts or nuts that hold the column up near the dash there should be enough clearance in the holes to center it or at least get it better.

I don't think you could move the column more than a 64th of an inch sideways on those two studs.

Mine was off a bit, not as bad as his and I was able to center mine.

Re: Shim for 1970 steering column

Thinking about it, if you were to shim two of the four mounting bolts between the lower mounting bracket and the column but only on one side, I guess it would tend to rotate the column up a little and closer to the opposite side, wouldn't it?




Doing that plus what Hank did also might get it centered
