The Stovebolt Site Forums The Shop Area Engine Shop Heater hose retainer clip position?

I now have a Harrison fresh air heater! In the 70’s as a kid when I first got this truck I used a heater from J.C Whitney. But now I’ve moved up in the neighborhood. So my question is was there a proper placement of the heater hose clip? I have the clip, but know I need to drill a hole through my beautiful paint job so I need to get it right. Thanks.
