l36 UIM swap to l26

so i tried searching this b4 i posted but cant find anyhting. as title says what are the obstcles for the l36 to l26 UIM swap??? i got leaks at UIM and the LIM so when it gets warm ima change the gaskets and UIM assembly.

I considered doing that swap once, but didn't want to shell out an extra $100 for ZZP's adapter plate

At some point I'll just grab an updated UIM: GM Intake "Sure Fix" Manifold Kit
