Well, DUH - this IS an overlanding forum; 1000 miles is just a shakedown run...:smiley_drive:
I didn't have to. My radiator and other plumbing is black so it doesn't reflect light readily.
I have read of others who have done the "Satoshi Grille Mod" who used mesh or screen material and suspended it from bracketry behind the grille.
For example, my Tacoma grille is one cast piece of plastic that has 6 bracket extrusions that mount to points on the radiator support with snap links; if grille transparency was an issue for me I would have suspended another layer of mesh from those extrusions.
I'm not familiar with the 100 grille mounts so YMMV.
Looks good though - obviously I agree with your enhancement, and I'd stick with the Toyota emblem, too. Th FJ60 grille emblem would look good on your grille since the opening is larger than mine - I tried it, it was just too big.
