CRT X1 CENTER DIFF 62t VS. 46T ???

thanks guys for all the help ....would it be beneficial to do the front and rear HB ring and pinion diff conversion with the 46t gear ?? and is that all the parts that would be needed (HB LST RING AND PINION ) to do the swap on my CRT diffs ??..thanks again guys for the help

...edit...would this be all i need to do the HB conversion on the CRT x1 ??
