Motorhome steering box interchangeable?

[chev-obsession]

So yesterday I found a motorhome with a tilt column. While grabbing the column I noticed hydro boost and a familiar looking steering box... the steering box looked identical to the Saginaw boxes on the 10-30 series trucks, however it was mounted at a more vertical angle than the 10-30 series trucks. The motor home said it had 27,000 miles and I believe it, it also looked to be a mid-late 80’s vintage. I’d like to grab it since it’s likely to be a quicker ratio.

Wanting to know if those steering boxes are interchangeable with the c10-30 series frames or if they differ in some way?
