I have one off a 454 tbi, that should be what you need. $30 plus shipping.

the 454 tbi bore is larger than the 305/350 but thanks

Why does that matter for the adapter. I think the bolt patterns the same. No problem either way.

Here is a couple pics.

the 350 Throttle body is smaller with smaller diameter holes than your adapter and are known to not seal and cause a loss of vacuum, IIRC the 454 bore is 2" whereas the 350 tb bore is 1-11/16”, but thanks
