Sara, i am not 100% sure, but arent the tail's in an explorer the same as the ones in a ranger? if so, i found a set of Carbon Fiber ones, chrome, red, green, blue, and purple.
looking at that, i got a killer idea. your underbody and cab neons are blue... what about blue tails? that'd look pretty smooth. the colored ones are about $175 and the Fiber ones are about $160. the chrome ones are about $150.
but here's a little idea that you should try if you are gonna junk your leaking alt's. get a dremel or something, and cut the lens off the tail. then get a purple magic marker and a blue magic marker. and start coloring. match the chrome to the same color as your underbody lights. then re-attach your lenses with scilicon or something, and see what it'll look like. that would be very cool.
questions/comments, PM me or whatever. and by the way, my name is Phil if you would rather be on a first name basis, i kinda figured Sara was a bit more relaxed than Alpha.
