The Stewart one is in my vehicle and I’m sure it was the silver one. The brass one had just came out of my car and you can see that is crusty with gasket sealer. The hole that you see is from me, I modified it when I installed it.
Also if you look online the seem to come both ways. Some are brass and some are not. The ones with the holes are there “modified “ version and the one I have is not and I don’t think that they offer a modified version for the mopars.
