Call Richie at Stangzone, he is in new port richey. That is where I got mine from. About 700.00 but the motor I got from him was CLEAN, so he was a honest seller and I'd definantly recommend him to anyone.
His # is 352-585-3205
Can't guarantee he'll have one but I think he goes to junkyards to find them, then brings them to his shop. Good luck dude
