I know- old thread- but... okay, I recently got a 1987 Schwinn Prelude with the Shimano Light Action derailleur. It had aftermarket friction stem shifters on it. I just came across a set of S424 shifters. I notice the specs for the Prelude in the catalog say "SLL-434 S.I.S." levers. Will the 424s work? Also, they came in a zip lock bag with all the parts loose. Can anyone point to an exploded drawing or provide directions about how to get these puppies put together?
