'70 Dart 392 Project; what direction?

Alright need some input. Got my ECU mounted in the glovebox and output bundles through under the dash. Like how it turned out.

Trying to decide on where to mount my quadspark modules. Both on one side or split them one side then the other? Any potential issues with either?

Also I couldn’t resist. Bought a battery and ran a ground wire to my starter solenoid and bumped the key… got a half crank from it before I let off. Least I did that part right!
