Is anyone selling or know of someone/place who is selling a conversion kit, and if so, for how much? and how hard is it to install one of those bad boys? Thanks. Pics of my 94 maxima are coming soon.

Try a pulling them off at a junkyard.If you buy them from the dealer you are talking$$$

please search next time; this is one of many questions asked so many times here
but anyway, here's the deal:

get BMW 3series headlights (not the latest generation, the one before that) from a junkyard, bimmer.org, or wherever

you will have to do lots of custom work to make it fit and take your time to do it right
here's a page with instructions:
