Old carb question

[phat46]

Which older two barrel carbs had three hold down bolts? Did the Stromburg 97's have three? The reason i'm asking is that i have an old Nailhead intake that someone wants to buy and i'd like to know what carbs can be used on it as it has the three bolt pattern on it. I see one on E Bay that looks like the same intake but it has four bolts per carb.

Yes, 94/97 are 3 bolt.
