seen a few sets on nloc.net not cheep though..just a fyi the 99 and 00 taillights are slightly different.
the 99 has 3 bulbs and the reverse is in the center and the 00-04 has 2 bulbs and the reverse is at the top...but in your case the 00 will fit all the way up to 04.
Are the 03-04 harley tails the same as the 03-04 lightnings, I found a guy that has a set he is willing to sell for 50, sounded like a good deal to me.
