Vintage Air 5/8" heater hose to LS water pump ? HELP.

[Tim john---]

I am installing Vintage Air and the heater hoses are both 5/8" coming off the V/A unit, my engine is a 2004 GTO LS-1 and the water pump tube connections are 5/8" & 3/4". What is everyone doing to mate the hoses up ? I can machine a tubular transition piece but thought most everyone here has gone down this path already. My preference is a 45° pre molded connection at the water pump for both hoses to route the lines neat and orderly. Options of pulling the water pump, remove the tubes and tap for fittings, use a pre molded 45° elbow and machine up a tubular transition piece, etc.. Please let me know what and how you accomplished the same. Thank You very much.
