OK to remove steering linkage to remove starter?

So I'm trying to remove the starter on my 1968 Barracuda, and the rusty-*** set of hooker headers are in the way among other things. I have the starter unbolted, but it is physically trapped in a cage of exhaust and suspension, so I cannot remove it. I am wondering if it is OK for a newbie like me to remove the arm that connects the steering box to the actual steering arms? it just looks like two nuts and a cotter pin. If I keep everything marked (for alignment), is this an okay thing to do? It would give me room (hopefully) to remove the starter and insert a new one.

And YES, I am replacing it with a high-torque mini starter :)
