IRS would improve ride quality from most people's perspective, I have a solid axle w/ 3-link, but have ridden in an IRS FFR before, good ride quality. The 3-link seems to be a better ride quality that the 4-link, which I have also ridden in. If I had to do it again, I would have gone with the Gordon Levy 5-link. This also depends on the horsepower/torque of the engine. Huge HP may require upgrading the components of an IRS suspension system, etc.

As for power steering, I have manual, but it is a flaming river rack and not a de-powered donor rack. If adding power steering, consider incorporating a Heidts valve as many have stated the powered rack is way to sensitive/touchy when stock. This valve reduces the power steering pump pressure.
