If I find a 60-66 long step-side what modifications would need to be done to bolt it onto my 1955 frame?

In the case of the '55-mid-'57s 1/2 and 3/4 ton longbeds, there is also a 6" difference in length, with the earlier bed being shorter.

Length is probably the biggest concern with this swap, the 60's beds being a lot longer than your 55 bed. Of course there are two different bed designs within the 60-66 series and it depends whether you have the 60-62 or 63-66 bed. We have detailed the major changes in our "Bed side interchangeability" article under http://www.mar-k.com/installation_hints.html.
