guys, thanks for the advice, which is also moral support to me! it ended well. i soaked in some liquid wrench, just what i happened to have laying around. it seemed to soak in very fast, so i left it a few hours. a friend who has stronger arms than me (all my friends do i think) took the pedals off, no problem. it seems a mirracle because i doubt i ever greased these parts when i put them together, but really, it was so long ago i don't remember. but they came off just fine and are now on my new Mondia, this time i know i greased them. once i get the bars shelacked i will post a few photos. still working on the squeeky mafac recers.
thanks much!
