small block oil filter adapter
Welcome to the world of rare. They used to be worth nothing, trashed, junked. If you needed one, head to junkyard. And other parts, too. Then one day, us Mopar guys looked around, and crapped. All our junkyard cars had been scrapped, and not enough demand to make it worth a company's time to re-produce them. China tries, but they suck.
Gawd, the parts I have trashed or given away......sob.
