From what I can see..... they still make it, it’s just not a -3 price code anymore.
It’s a -5 now....... 20-418-5.

It’s ground from the “dual energy” lobes, which are pretty mild and made to be easy on parts.

Since a -5 is the same price as a custom....... I’d probably do something a little different for that $$$.
