I recently replace my NP207 with an NP231. Now the old case is just taking up space. If anybody wants it, you can have it! You pay shipping or pick it up in Mena, AR. It's not perfect-the reason I replace it was because it wouldn't engage the front drive shaft in 4wd low. Seems there was a leak that I didn't catch and the dry gears wore down.
Also have the speedometer drive gear, which is hard to find. Just send me a private message and we'll work out the details.
