It's about time to replace mine and I never paid attention as to what the original set up was. I kinda like the feel of them so I may use the same kind if I can find them.
Rickenbacker puts strings with gauges 105 75 55 and 45. You can order direct replacements for them from rickenbacker or you can get some other strings (DR, Rotosound, etc) but they'd be in slightly different (and more commonly used) gauges like 105 85 65 45.
