Natcho, if your car is already on a rotisserie, then sure you can always do it that way...most people like me add the connectors and boxes during restoration/mods, and can't afford a rotisserie restoration.

Me neither! But will be installed before assembly K member, axle, engine etc... still on jack stands . They will be regular tubes like the MP ones but will be tricky since is a 74 Charger ( isolated t bar cross member is in the middle ) so will be installed diagonally to sway this piece, just right at the front frame rail junction.
