Damn, you never installed those!? Absolute mf'r to build; I only built one other set that was brighter a few years later. Very few could come close to out driving the light output on those... Great buy for some looking to massively upgrade the factory candles.
It's rather simple. NO cutting is need on the sports bumper, however, you do need a cheap facelift bumper to cut up. The headlight area is what needs to be modified, specifically the little wing that pops up.
Short answer is no, not stateside. Long answer is you don't actually need the crash bar, the USDM one can be trimmed
As for a grille, yes, I have a few options available.
The plan was to convert it to REV d/f, but I'm out of real-estate for storage of personal goodies.
$300? Still on the fence, lips for this bumper are damn near impossible to find.
