Im sorry it took me so long to get back to you , but the meritor axle is a MFS06151CNN3, the king pin kit is R201478. The new king pin has to be machined where the draw pin goes through to fit the new draw pin.
You could use the old draw pin, or go to a diesel shop and ask if they keep the have any used draw pins and get one that is the right size, one that you can bolt up. The drag link is the next step, you'll have to weld the original drag link to the drag link that goes with the meritor knuckles, it lines up well. Me I'm using the power steering box off a 97' Intertional 3800 school bus. I'm not sure if your engine will produce enough vacuum to work the brakes or not I'm using the hydraulic booster off the 3800 bus. If you go this way keep in touch so we know how its going.
