Man a heater core from a junkyard is a gamble...never know if it will leak or not. Advance auto parts ranges from 69-135 dallors for a couple different kinds, but what ever does the trick for ya I guess. Call G&G auto recycling @ 1-800-368-0854 and talk to Scott, he can always help out in some way. The are located in Winchester, but are on the network so they can look all around VA,MD,DC etc.
