Throttle Body Shaft

[BowlingSS]

I was going thru all my carb parts and noticed two throttle body shaft length. What years are used on the longer shafts? My 70-73 carbs I have use the shorter shafts.

I’m going to guess and say I would think the longer shafts fit the BS38’s that were linked, so ‘76-79?
