TRAJ> What size aftermarket pulley will work with a Simplex derailleur?

I'm not sure if this is true for all Simplex LJ, but the one i got (LJ
Super, looks like http://www.parkcity.ne.jp/~meisei/craft/j_slj.htm )has
dural alloy bolts for the pulleys with a larger diameter than standard
pulleys (6mm instead of 5mm or so? it's been a couple of years..).
i once tried to replace these with standard ones once and failed because of this.
