does anyone know this 340 Duster?

My coil is bolted to the firewall in my 72 Duster, I think it's easier to work on/around the distributor with the coil on the firewall instead of the intake... I'll leave mine there till I go HEI.

Whatever. Still looks like a shadetree job mounted there.

I run mine mounted vertically behind the intake. I use an AR Engineering bracket, you can get them from Hughes or Mancini. Much cleaner, much easier to deal with, looks like it should actually be there. The picture is from the mancini website, obviously it's on a big block, but the Air Gap manifold on my 340 has a nice mounting boss on the back that works perfectly.
