They won't be able to help Peter, All Lancia Volumex Coupes, HPEs and Trevi Volumexes left the factory with power steering. Also, the shape of the inner wing precludes running a belt from the crank pulley direct to the supercharger, it has to follow an L shaped path from the crank pulley forward to the tensioner, up and over the supercharger drive cog, down to the power steering pump drive cog and back to the crank pulley.
I've never seen a Fiat 124 Volumex up close nor the Argenta VX to be able to describe the belt route but I'm pretty sure the 124 VX wouldn't have had power steering. However, with an upright installation the inlet manifold might be different?
