vacuum line, what size ?

I have a 350 / 350 setup in my 50 chevy pick-up and it currently has a long hose being used for the vacuum line on the tranny. I know this line should be steel. I have looked for a stock line, but having a hard time finding one. My question is, what size brake line 3/16 or 1/4 has others used, or does it matter? 3/16 is easier to bind and cleaner looking but is vacuum volume an issue. Thanks

No volume issues. 3/16" is plenty. It never really "flows" much, just enough to yank on the vacuum modulator so small is fine.

The smaller the better actually so there is less air to move... 1/8th inch would work great...
