RovahFarm for all your new Land Rover Parts and Accessories
The second one down is what you need, hung one on my 2.5 two years ago. If your ex MOD has the extra brace to the block at the front of the starter, it will not work with these new production starters, but this doesn't seem to be a problem as not all trucks had the additional brace.
My slow starter was partially due to a bad chassis ground, which probably contributed to its demise. Sound like you are on top of your connections though.
