Headlights

[99Ztwenty8]

I recently received the Halo headlights that i ordered forever ago (different long story) problem is i am having a hell of a time trying to get them in. The old headlight came out pretty easy one bolt and remove the bulbs. but this new one i cant really understand why it wont go right in. It is the same size and shape as the stock...so its the right one, i have read that its difficult because the weather stripping is supposedly thicker on the new one. does anyone have any good tips for such a problem?
Thanks in advance guys.

lubricate the new seal with K-Y jelly. Will help it to turn once you shove it real hard to get it to that point. AS soon as you get a little turn on it it's down hill from there.
