Joseph,
Keep in mind that as mentioned above not just any SSD drive will do.
If you search eBay you will find many SSD drives but note that many are 2.5 inch drives designed to replace the typical laptop hard drive. The Macbook air original hard drives are 1.8 inch drives (ie not as thick)
More importantly the connectors and connection method must be the same in order to perform a simple swap as you desire.
For A1237 the original Air version the connector is a ZIF (Zero Insertion Force) connector and the connection is PATA. For the A1304, the connector is a LIF (Low Insertion Force) and the connection is SATA.
There are not many drives that work. One is Runcore Another is Photofast.
It would be a good idea to review this thread that discusses compatibility of SSD with macbook air.
Hope that helps.
