No , the only compatibility for a 1970 Chevelle is a 69-72 Monte Carlo, Chevelle, El Camino... hope that helps...
You can make it fit, but chances are the wiring harness will be different as well as the length... Especially the length. You can try it if you have one laying around, but I wouldn't pay for a '72 steering column if you are working on a '75 Chevelle. now, a steering column from ANY 1973-1977 GM A-body should work just fine, so if you can't get one from a '75 Chevelle, you DO have other options.

Standard Saginaw steering assembly common to most North American autos post-69 (I think) is a good one. Also, autozone.com has online manuals, for examples please refer to the related links.
