1971 240z Licence Plate Lamp Photos

[240260280z]

I am posting some photos of part details as I restore. Hopefully they can be of use in the future.





















I painted the light compartment white to improve output.


Heat Shield (seems like engineering correction to alleviate melting plastic)




7.5W






Retaining nut in place.










Light leak at top edge. Gasket does not seal.

We have new ones if you would like see what new one look like.

Nice, thanks for putting in the effort.

Sure Esprist,

Please post them to this thread.

Wouldn't it be great if every Z part was photo documented in a separate thread on this site? hint hint

Here are pics of new part:

Note the inside is black plastic so the outside is painted a metalic grey-ish colour.

Here is the hardware for reference (1 clip is missing)

Nice picture gallery.  I'm in the middle of the same process, working with a combination of the best parts from 3 separate units.  In all cases, to a greater or lesser extent, the black plastic housing has warped from excessive heat.  I wonder if this design might be a good candidate for LED lighting.  Anyone tried this?

 

Also, the gaskets in all of my donor units have torn.  Any thoughts on where to source a sheet of 1mm-thick neoprene?

You are lucky to have a few to choose from!

The replacement LED is part 1895.

It has to shine down 90 degrees to the socket axis.

An LED would run cooler and enable removing the metal heat shields.

Fill the socket and connections with dielectric grease.

craft stores such as joanne fabrics or michaels (west coast chains) sell foam sheet with a self-adhesive peel-off backing, used for making stick-on decorations. i've used this material for non-critical sealing and squeak-fixes between interior parts. industrial fabric shops that sell fabrics/supplies for upholstery, outdoor equipment etc. (we have seattle fabrics out here) sell neoprene in many thicknesses.

Thanks for this.

I just finished installing this part.  Fortunately I had two in the shop, because after carefully cleaning and painting the first one, I discovered that the centre mounting hole was waaay to big.  Someone, somewhere in the past 44 years, had apparently tightened the bolt too far, and punched out the hole.  

Cleaned up the second one and it seems OK.
