Northwest Nova

Nova Hood Latch Reference & Identification Guide

These parts changed basically whenever the design (shape) of the grill changed.  You will see a lot of similarities between years, but they are not interchangeable outside their designated application.

 Buyer Beware...

→ Part advertised as wrong year(s), this includes reproductions!
→ Bent or distorted from a front-end collision (extremely common)
→ Hood latch center main spring broken
→ Parts frozen from rust

Good used parts are common enough not to warrant repair of badly damaged units. NOS pieces pop-up from time-to-time.
