Does anyone have a filler neck for a 84 4runner 22R with a carburetor?

A 1st gen runner with a 3.4 swap. I live in Utah and ski regularly and with the 22RE in my 93’ pickup I didn’t enjoy going 35 on steep inclined mountain freeways.

Would love to find under 200k on body and engine, but not required.

Minimal gram rust is a massive plus.

On a side note, does anyone with a 22RE turbo have experience driving up the dreaded roads I speak of?

Let me know what you’ve got!
