I need clarification on the correct method to replace power steering ram seals?

[Jim S]

I am replacing the seals in my power steering ram on my 72.  I started the procedure according the instructions in the shop manual. It stated the order as; inner seal, then bushing (I used the steel bushing that came in the kit), the dust seal, outer seal then the scraper.  I found that stack of parts made it impossible to install the snap ring.  Now when I dissassembled my ram, there was no steel bushing.  The diagram on the kit instructions does not show using it as well.  My assumption is don't install the bushing and the snap ring will seat.  Any one else go through this?
