x-trail splash guards

Dear members

I need help to find a scale diagram of the left and right splash panels/guards thats protects the bottom of the engine and fold under the fender.

I got a engineer to fabricate the two plastic bits out of stainless, but he need the dimensions.

I got the workshop manual, but regrettably it's not in there.

Also if anyone knows the diameter of the diffs front and rear, shift spline, ration size and make.

Getting a diff lock for the x-trail but nee the following information. Thank you all.
