Please help me identify my column

I recently bought a floor-shift steering column off Ebay. The ad said that it came from a 1971 Demon. It's in pretty good condition - all there and has the Tuff wheel adapter. That's all fine and good.

However, when I look at the lower part of the column jacket on the column that's in the car right now, the 'mesh' part is diagonal, like a chain-link fence. The one I purchased has vertical slots. I'm thinking I may have the incorrect column for my '71 Dart.

Can someone enlighten me to the differences and if I made a mistake?

Thanks,

Greg
