I finally made a 1st copy of a radiator cooling panel for 240sx / S13 (89-94).

It fits "ok." The edges are a bit rough. The hood does close and open properly. It's made from 20 GA steel with gray primer finish.
Im still in the process of creating our (Sun Belt) own special design.

Heres a pic of it in gray primer, and at the bottom is the "real" cooling panel.
