Velocity Stack (Air Horn) for 40mm DCOE - Size question

[mofares]

I just installed a set of 40 Italian DCOE's that have been lying around for decades on my car along with all the parts needed for the conversion. It runs I currently have a set of new oval K&N type filters but I would like to go with stacks and sock filters.  I have read many many threads on 40 DCOE velocity stacks (trumpets) but I am still unable to come up with the proper size stack that would be needed for my car with the stock brake booster. Ireland is out of stock of their angled ones but if someone can tell me which stack would fit that would help me immensely before buying them. I am suspecting 40 - 43mm (1.69") but unsure .  Thanks in advance and feel free to IM me.

for my 45 DCOE. When placing the order just leave a message in instructions box indicating 40 DCOE

What manifold?  A longer manifold means less room for stacks.

And what goes between carb and manifold.

Cannon manifolds no soft mounts.
