My favorite classic Stronglight cranks are the drilled ringed 104bis and the ever-so-lovely and super light 106 (which is a dead ringer for Campy SR cranks). Those two Stronglight cranks would enhance the looks of any 80's classic bike. I could certainly see both cranks on an 80's Falcon.
Both those models still come up regularly from French Ebay sellers. Only thing with the 106 is, it's 144 BCD ring bolt spacing is starting to be harder to find outside of these french eBay sellers. I went to a "respectable" bike shop in the SF area last year looking for replacement rings for my 106, even if I had to get a non-Stronglight brand ring from them, and the sales people didn't even know that rings come in 144 BCD!
