A few nOOb ?'s

Will the later xj windshields w/ rubber molding retrofit to my 1990 xj with the 4 chrome trim pieces?

Will a H.O. IAC work on my 90 Renix?

Thanks.

Yes on the first. Use the rubber trim as well if you can. Some people advise that when you do this you snap off the little studs that the metal trim attaches to, but when I did this on an 87 it was not necessary.

I'm not sure about the second.
