There are a few different ways you can do the transmission. You can used the whole setup out of the Dodge and just use the driver side drop D60 out of the Dodge. That works fine although it isn't the normal Chevy passenger side drop. Also that offers more room for the exhaust on the passenger side. Or you can go with your idea of finding a older Dodge np205 or swapping the main shaft to 32 spline. Since you already have the Dodge I would just use the axle.
