Mystery drain c*ck

[78_Monte970]

I have a 350 swap in my mc and it has an aftermarket radiator of some sort and neither napa or oreilleys has a replacement. It is missing a clip that fits into the keyhole in the rad. No part number, is it oem? Any identification help appreciated. Thread size 3/8 npt

I tried this one. Close but not quite. Mine is 3/8 thread. The keyhole is also rounded and the clip on this one is square

The clip (square) is stuck in the radiator. It comes off the drain plug easily.

if it requires an npt plug what about threading a brass npt fitting into it?

The threads are deeper into the opening, and you loosen the cap on the openimg and theres a little drain spout. Seems more like 90s early 00s tech. Any popular rad swaps from cars of that era? Seems they had to bash the top of mine down to fit.

Gwarren 79 was right... it was stuck. Upon attempted removal it started breaking and eventually fell in. I dont think it would block anything and i reason it would withstand temp, is it ok to leave it in there?

It will be fine in there

Thanks for the help. Sometimes you just need to look a bit closer before trying to fix 😂
