MSD box mounting locations

[Berg]

Any of you guys out there have any pics of where you mounted your MSD ignition boxes? My car originally had it mounted under the dash but not done nice. I decided against keeping it there although it does keep the underhood side cleaner. I am thinking about putting it on top of the heater box on the firewall. I figure it should be a fairly short run for the wires and my car has plastic wheel wells so that idea didn't seem too hot. I thought I could also run the small wires through the factory firewall gutter and snake the main power wire inside the passenger side fender to the battery +. I decided to run HEI for now with it and already bypassed the module in the distributor. I'd like to see what it actually looks like there before I drill holes and mount. I guess my other option is Velcro for mock-up.
