Petcock ideas?
I have a 72 and the radiator drains directly onto the frame extension crossmember. I'm looking for ideas to redirect the flow away from the frame.
I started with a 90 degree street elbow on the radiator (pointing rearward) and an extention pipe coupled to a standard petcock. That works with one exception, and that's getting the elbow to point in the exact position needed so the extension will clear. As my luck would have it, I had to back the elbow out just a bit (a quarter turn), and I'm concerned about leaking at this point. I don't want to force nearly a full turn more to make sure it's tight, especially since this is a new radiator!
Idea #1: Drill a 1" hole in the crossmember, remove the elbow and run the extention pipe straight up into the radiator.
Idea #2: Go back to the 90 degree elbow idea, but this time JB Weld it in place.
Anybody get creative with this before or can offer some other ideas?

Maybe something like this and clamp a hose to the end?

I had petcocks on both sides of my block and the regular one on the radiator. I made a little u-shaped channel, with one end closed, out of tin foil. I opened the radiator petcock and then slid the tin foil channel under the petcock and hardly lost any fluid doing it. I know it's just a temporary thing, but it worked fine.
