Well, images of Sporty haunted me while I polished the heads of bolts and slippery little cable hangers and what not, thanks for the inspiration and help along the way PB
I was able to buy a Stem from a really nice guy on the Schwinn forums, it's the skinny 21. something one, I just have it lowered almost to the point it flairs out, I don't know if it's correct to the year or not but I think it came from a super sport, I've seen a few different stems on these old Sports.
