Wow, it looks so much better! I think the tall skinny tires are the way to go on these.
The lights on the front you mentioned wanting to replace, are they the turn signal lenses below the headlights or the cornering lamps next to the headlamps? The factory cornering lamp lenses are clear and light up when the turn signal is turned on like
@FJ40 that green thing said. It would appear that only the RH side turn signal lens is available from Megazip, Partsouq doesn't have either in stock.
I have always used Auber digital gauges for pyrometers, they're pretty good for the price and I feel they fit in dash nicely. My first one I mounted in a single DIN cubby below the radio, my brother has one mounted in a switch blank in his HDJ81, and I have a double DIN mounted in the dash pod on my current Prado.
