Waggy axels are only 1/2" wider than your stock D30, not a 35 that's a rear axle. A D44 is a bit over kill for 31s and they came with 4 bolt patterns, none of which are the 5x4.5 except for the Rubi version which is a 30/44 hybrid and the same width as stock. It's going to look pretty silly with full widths and 31s. Just find some wheels with very little back spacing and it'll get you pretty wide. I ran 10" rims with 3" of back space with stock axles and it wasn't much narrower than what I have now. That being said don't run a 10" rim with you 31s unless they are 31x12.50 and even then I wouldn't advise it.
