Hello everyone.

I need to rebuild some Rover differentials, I've been doing research and I need a comparator block, Code LRT-54-503
Any recommendations where to buy one? I will need dispatch to Chile.
Also a second-hand one can work for me.
 Thank you.

This is the current supplier, but you may find it easier to buy through somebody else (like a LR dealer). Bosch require an account to be set up and pre-pay system which moves slower than the average glacier. Let me know if you get no joy an I'll see what I can arrange.

He does the backlash adjuster too.

Is there a simple delete option for a spotted duplicate posting?

From Chile, buy it on Ebay, between shipping and tax, it would cost me 180 pounds

My understanding is that the pinion height is 1.5" below the bearing saddles plus or minus the value marked on the end of the pinion, for the 3" od carrier bearings. I bought two slip gauges off ebay to give 1.49" and a length of 10mm ground silver bar to place across the bearing saddles, and then used a feeler gauge to check the gap between the sip gauge and bar.  I think the slip gauges and bar cost about £20.  Alternatively a machine shop could produce a length of 25mm bar to 1.49" and check its precise length with a micrometer/ vernier.

Interesting option. Thanks for comment. 

"My understanding is that the pinion height is 1.5" below the bearing saddles plus or minus the value marked on the end of the pinion"

Could someone confirm this measure, perhaps one option is to have a standard block manufactured with the specific height... perhaps it will be more economical for me... I only need one height, not three heights as the Block that is sold has.
