K-frame is different, stock. Schumacher has conversion mounts, I'm sure, if you don't want to change to V8 K-member. Wire harness, exhaust, radiator, looks like you have a grasp of things. The harness will probably be too long in places, so it will still work. The oil sender wire will be too long, for instance, but that's better than too short. For console, you need the console, shifter, mount brackets which are welded to the floor (three I think), linkage, brackets. The small block transmission will need a boss on the bottom of the tail shaft to mount the bracket for the down linkage from the shifter. Some don't have it. The driveshaft will be the same if using another 904. Someone will probably say something about brakes. The small block weighs the same as the slant six, so they will work as intended, but I think even a slant six car could use an upgrade in this department, so it's up to you.
