I'm actually converting my car right now if you want to follow up on my progress here:
Nismo Conversion
I intend to make my own bracket, the little stuff costs way too much. I am going with Black plastic clips instead of the Nut with screws. The last thing I want to do is spend ton of money on little screws, Fender Liners covers, brackets. But at the same time, I'm trying to not skimp out on parts that make a huge difference in looks/function.
