There's an auto upholstery shop in town that is very well regarded and while
talking with him regarding my car I got to wondering if I could pull out my
Cherokee seats and have him leatherize them.

Yes.



Hmmmm. Does "repair upholstery" cover "replace with leather"

Yes.


(or pleather
for that matter)? Does taking out a seat constitute "disassembly of a
primary structure"?

In the vast majority of cases, no.


I'm pretty sure other people have done this but I was
just wondering how "legal" it is.

Perfectly.
