19 70 driver side exhaust manifold interchange

So I'm pretty sure a standard head pipe for the driver side will work. The passenger side is using a truck manifold which looks identical to a manifold that I took off a 360 duster so that actually might be a standard manifold. Also been communicating with accurate exhaust for a week now. Their main tech guy has been out and I have not been able to get an answer from them and whether this will work
