slant6 dipstick...

If I had one I'd probably ruin it trying to get it out (from the top anyway).
Aftermarket or repop stick and tube may be your best route.

i haven`t checked with Mopar for it, but i`m sure its overpriced (for my wallet at least) but for the heck of it i did check Year One. they don`t have it... i guess they don`t see slant owners as a viable market! oh well. (they do have them for V-8 cars)
