What steering coupler do I need?

I am looking to replace the steering coupler in my car. The car in question is a 1971 Scamp and it has manual steering. I looked them up on a few websites, such as Summit and Mancini, and I kept finding the Borgeson 036425 coupler (and that was the only one offered by Mancini, aside from the FR one) so I figured that is what I need and I ordered it. My buddy says this is what he used for his ‘70 Duster, same basic application. I later noticed in the description on a different website it says something about the Borgeson power steering boxes.

So, did I order the right thing? I’m not looking to do a power steering conversion, I’m fine with manual steering.
