B body manifolds will fit fine. Just have to trim the steering column outer sleeve.
4 speed or auto? I tried the b body manifold and the downpipe runs right into the z bar, dead center.
I'm going to guess the green car is an automatic as I see in one picture a big red cable going thru the clutch rod hole.
If that's the case with your car G340 then that would explain why Chrysler didn't use the B body manifold. The TTi Z bar just kicks the one of the bars that connects to the linkages off to one side further , I think it's the one back to the clutch fork , it doesn't change anything with the tube going between the inner fender and the bell.
I think the C body is going to be your best bet , unless you want to spend money on Rhinos manifolds, but the engine will be better off in the car to figure out that headpipe routing.
