Yep, the back is the easy one...have fun with the front!
That is the nive thing about the Zu 12 bolt, 9 inchers, and Toy axles. You can just remove and replace the third members.

Marlin...the 478's are ideal for 33ish tires on the VX. And unfortunately are about your only option if running the stock 10 bolt front end. For 36ish tires 538's are probably better...but that would require a solid axle up front.
