The 631/2 crank is outside the time limit, being from the mid 90s, but...

The catalog mentions that it will take a 44 tooth outer ring with the shortened spider arms and also that the front derailleur adjustment is easier with 8 speed (clearance issue), but Mavic's front derailleur was available until Mavic stopped offering a group, so I don't believe the change in the crank arms was a result of Simplex's demise.
