A hose barb. Clamp, then disconnect the hoses from each side, then connect together with a hose barb and clamps. You don't
have to bypass the TB though. It is suppose to help with cold starts by heating the incoming air. How much good it does or not, or how much power is gained by eliminating the heat, I don't know. Mine is still hooked up, although I will probably do away with it and completely grind the fittings off of the TB some day.
That of course would be on an OEM type set-up. For a conversion, you can do a few different things. Starting a the steam pipe on the drivers head, you can just forget running it to the TB altogether an either 1] drill and tap the top of the water pump and run the hose there, 2] run the line to the radiator if yours has a nipple for a heater hose (most 67-72's and 73-91's did), or 3] use an adapter from Jags That Run and tie it in to the upper rad hose.
Tapping the water pump is the shortest and cleanest way to do it. I did mine like #2.
