I'm going to do the same thing! Did a similar swap in my old furd, put subaru seats in. For the Dodge you'll have to be sure if you're using the center console ( I will be) that the seats will fit without looking stupid as some seats are just too small. then ,you'll have to fab all the new mounts as the factory 40/20/40 bench is all one piece. you'll do this by mocking the seats where you want them then making the needed "legs" to the attaching points, tack together check and recheck all measures and fit ,including driver/passenger comfort and back seat access. then finish weld and paint. you'll also have to figure out seat belt arrangement if you have a QC . Post pics of course!
