You might consider buying that. If for nothing else than the solid-axle D44. That's the same exact setup that WelderScott has - I know 'cause we just worked on it extensively yesterday. And that solid axle/coil spring setup is a good one.
However, I don't know how hard it would be to swap it into/under a Bullnose. I don't know if the radius arms are the same length, meaning that the Bullnose brackets are in the correct place. But it might make for a good 4x4 setup.
Also, getting an NP205 for $100 is a good buy in and of itself as they are supposedly sought after.
