Need help determining correct fitting between fuel line and carburetor

Have a 68 barracuda 340. Original fuel lines to carb back then were all hard lines. Original carb was a Carter AVS 4bbl.
Fuel lines have been changed to hose by a previous owner. Carb has been changed to an Edelbrock AVS 2.
I want to keep the Edelbrock carb as it works well and is nearly identical to the original Carter carbs.
I would, however like to restore to original style hard fuel line and have ordered lines from in-line tubing.
What I need help with is identifying and finding the correct fitting to couple the new in-line fuel line to the Edelbrock carb.
I believe the in-line flared fitting to be the same size as original stock design. I also believe (but have not confirmed) the inlet port on the Edelbrock carb is the same size as that of the original Cater carb.
Anyone done this before and know the fitting and where it can be found?
-Thanks!
