looking to buy Matrix rear wheel for older Trek
 

I recently got an older steel trek with mismatched wheels. Im looking for a rear wheel, 700c, 36 spoke, for a 7 speed freewhweel to match the one pictured. It would be a plus if it is in the New England area, I don't mid driving. Thanks in advance,
