Has anyone found a match for the textured dark argent ('68-'69 Road Runner grilles & etc)

Aarrgghh; thought I had a couple cans of the Krylon 2521 left, but nope.
That was a very close match for the factory finish.
Apparently discontinued, not available on Ebay, Amazon, or the stores that show up on Google.
A couple restoration-paint sites claim to have the right stuff, but at $24.95 for a can, I'm not inclined to gamble.
If I need to buy a quart, so be it, as long as it's right.
