Thanks Thomas. I did order the 2400bps one, I didn't specify that I was seeing if this could be done for the transmitter RF Link Transmitter - 315MHz - WRL-08945 - SparkFun Electronics
Since the crystal on that has 315 on the packaging I was hoping to get one just like it only @ 310mhz. I was hoping it'd be as easy as swapping them 
Thanks again!
