Here are two valances, one is recognizable, the other is not.

The brackets on the short one are definitely Datsun, but too short for 240z.

280Z is my guess.

The short one looks familiar.  280Z.  Looks in decent shape, hang on to it.  They get crunched by curbs and shrubs and floor jacks.

Part #10.

Never spent time around 280z. I always thought the major change was just the US bumpers.

Thank you.

 

It is a 280 center valance. The lower and larger rad opening and bumper changes required the 280’s to have changes in the shape and fitment valance components. They are are interchangeable with the 240 parts. Even the signal/marker lights were moved out of the outer valance pieces
