Hoppers Stoppers say they make a brake kit for the KE20 which includes custom made Ford 5 stud hubs, I'm sure they would sell you just the hubs if that's all you needed.
Other than that you would require different struts to fit 5 stud hubs and that opens a whole can of worms on these old KE's as it'll mean a few other items will need changing too.
So you're running a KE30 hub on the KE20 strut at the moment??
