hey all just wondering if anyone knows were i can get good parts for cheap i lost my right part of the front bumper and also the right signal and parking light.

The best person to call for LR parts is Mohammed, here's his site>> http://www.rovercity.com/ his site is under construction, but he will help you out if you give him a call, and he is really good to work with.
Best,

If you remove the front screw from the trim that is on the outside of the passenger side and the sill plate,you can pull back the cover enought to see a LED readout.Turn the key to the on position .Not to start.If there our codes they will show up on the LED display.
