Rear heater lines-is 1/2” big enough?

[69LC]

A while back I bent up some SS 1/2” lines to replace the blown out steel.

I’m prepping to re-reinstall the engine and tranny and now is my moment.

Do you all think 1/2” will be sufficient?

If I recall I still need to finish bending the longer two and welding retaining beads on.

You may be able to sell a bunch; will you reuse the original mounting brackets, flaring the ends where they attach to rubber lines, painting or coating the pipes, covering them with some sort of heat wrap??
