You may have success reforming the pins for a tighter contact. A drop of
DeoxIT from Cramolin can help clean dirty contacts.

Pins and shells are available from TenTec parts and Mouser Electronics
(www.mouser.com). They are Amp Universal Mate-N-Lok series, not Molex.
Shipping will cost more than the parts for a complete connector.
