It seems crazy to buy a Stronglight puller just to get just one crank off. (They cost around $55 at
Velo Orange),.
I'd recommend going to a bike co-op if there's one around you. They probably deal with old French bikes and have a puller you could use for much less $$.
So, for now, put the crank on and worry about the puller later.
