Vulcan 800 and 1500 are metal 7 inch bottom mount, and the mounts are really close to what our small plastic junk bucket uses.
VS800/1400 is the same part number as stock Savage/S40.
The locomotive headlight is a 10 inch, and the gentleman that owned it (not Paladin) is deceased.
I run a high set 7 inch metal side mount. British replica with a traditional looking lens and H4 bulb. Mount it high, and you have more room to dial in where the beam hits in front of you. Side mounts allow you to perfectly dial where the beam hits in the lane or shoulder. If you buy a side mount, go ahead and get the Emgo mounts and bucket, just paint them and replace the hardware with stainless before installing. You can buy Triumph replica turn signals that mount through the headlight "ears" and delete the factory plastic junk from your forks at the same time.
Best parts swap ever on either of my Savages is the combination of full rear fender and high mounted headlight. They make the factory installed 1920s Scott (long out of production English bike) knock off fuel tank look good.
Tracker or touring handlebar will complete the look and dramatically improve the bike's ergonomics.
