Fuel tank sending unit

Just got the tank apart on my 74 Dart Sport and I am in need of the sending unit/pickup. Where is a good place to find one?

EDIT: I have found some, but they don't match what I have.

check with JSBrown on here on Moparts. Works right and a shipping break for members. He checks them before selling.

e-bay. or your local parts store. Unless you have a hi-po motor the stock unit should work fine.
