Hello all,

I am currently doing some research into how the old (Roughly 1970's) rear plastic light clusters were produced. I presume it was through some sort of injection moulding?

Does anyone have any information on this area or relevant links.

Specifically I have a 1972 Datsun Cherry (Lights made by Koito) and am interested in what manufacturing processes they would have used. Also any ideas on the type of plastic/polymer these 1970's cars may have used for the light lens?

any knowledge around this would be much appreciated

P Dennis
