Rod Bloomer ( BPE ) used to offer them.
I was messaging with him yesterday for my stroker deal , and he is having delivery and tariff issues so inventory was low.
He had nothing for me in a 2.0 or 2.1 rod journal for my 360 block.
Short of having a billet crank made for you , I think you are going to have to get lucky and source a used or NOS part.
There are probably a couple that got bought and the project got put on hold for what ever reasons.
But new is going to be a problem.
