Debbie I usually drop off my bikes for repairs, they may have used parts that can save you quite a bit. If you can not find used parts they can order new ones and they are the most reasonable aI have found.
They've fixed up several bikes for us and done a great job. Give them a call if you want to confirm before making the trip, but they can probably help you out.
You are probably best off bringing your bike into the shop. 2nd Cycle does some service, but their specialty is teaching people how to do their own bike repairs.
