Replacement Headlights

[staindvans]

i was wondering if there were a difference in the headlights between the earlier jeep libertys and the later ones. i have seen replacements on ebay for years 02-04 and 05-07 but sometimes there is one where they overlap. i'm talking about the headlight housings not just bulbs. was hoping someone that was good with part numbers could help me out.

thanks in advance
