What year did Chrysler used these aluminum versions on there 340?

i always thought those were the adapters offered by direct connection.
as far as i know, [and i have been wrong MANY times !] the right angle filter adapters on all original engines were the iron adapters.
someone with more knowledge than i possess will hopefully chime in with the correct answer.

I think there are later applications that got aluminum version.

In 1968-69 they were cast iron.

Cast iron on every 340.

i remember back in my junkyard ownership days, [1972-1984/5] the 68 & 69 340s we got in had the iron adapters.
i really don't remember about the later 340's.
i also can't remember about the 360 oil filter, although i'm thinking they were a shorty filter, and mounted to the block without the right angle adapter.

so, the spiders in my old noggin' didn't cover up that memory !
thank you sir.

As already stated none, over the counter DC items. And DC used a few part numbers.
Keep in mind on factory cast iron ones there was 2 angles one for early A bodies and one for later cars. Puts the oil filter diff angles.
Also later M Bodies and a few more full size cars got them. They are the cheaper easier to find ones But the later ones had diff appearance " had gusset looking things added " if that matters to you.
Here's a DC one you can see the part number so if you see one painted
