Coolant Hose ID measurements

[architect]

Hello,

I am in the process of replacing all my hoses.. it looks like the previous owner decided to play a game of mixing and matching

1978' Fiat 124 - 1800

Will someone kindly suggest the I.D. of the hoses below:

1) larger hose from thermostat "pipe" near the exhaust manifold -> to the heater core in thru the fire wall 16mm or 5/8"?

2) larger hose from firewall heater core -> to head (assuming same as hose #1) 16mm or 5/8"?

3) smaller hose from thermostat "pipe" near the exhaust manifold -> carb (choke I presume?) 8mm or 5/16"?

4) smaller hose from carb to block (near hose #3) (choke I presume?) 8mm or 5/16"?

5) larger hose from crank case -> intake filter? 16mm or 5/8"?

6) smaller hose from radiator cap -> to overflow? 8mm or 5/16"?

Thank you!

with the fiat vendor price of the hoses, why would you make them, or try to find them somewhere else?

I just finished up swapping all hoses... here is my findings for anyone in the future.
