Hi, forgive me for my ignorance as I am a newbie. I have a 03 GX470 and I was given a 2017 LC200 rear 3rd member for free together with the matching front 3.90 gear. I am planning to buy the Diamond axle housing to make the 9.5 LC fit. The LC has 32 spline vs the 30 from the GX. What will it take to make it fit in the GX while I want to keep my wheels and tires and I am just trying to beef up the rear axle and hopefully save money vs completely doing the Diamond axle setup.
