I think they look pointed down because of the angle of the picture..
Check out
www.73-87.com. There are two different write ups on putting Autometer gauges in the original locations, one on top (as I showed above) and one behind. The write up with them behind the gauge panel for some reason the pictures aren't working, but you might be able to contact the webmaster (a member here) and see if he has those.
Nevermind, found the pics...
And a straight on shot of the ones I posted earlier.
