Yeah I hung my Peel 'special' 3 phase Podtronics on chin of bat box too but that was a get away with any thing special not the more disciplined thought/effort an all factory looking Commando like Trixie takes. Could just strap it under the spine or maybe on the gussett at top front of batter area. Nothing wrong with modern rect/reg, same as Miki carbs, but who wants everyone to know you gave up on the old ways on just a fast glance over?
