Indeed it is... I believe they worked off the power steering pump, hence all the additional fittings and hydraulic lines hooked to the back of it. Probably the only 69 camaro I ever saw with a setup like that! Looks like the alternator came from the same truck...
I like how when you click on the link to the "Immaculate Trunk" it has an arrow pointing to the tire and jack, like you wouldn't have known what that was without the diagram.
