I tried the Weathertech. It didn't fit.
Factory mat is only listed for w/o rear AC.
Anyone know a mat that fits?

Maybe I'll just cut my own.

 

I have no idea.
I have a Weather Tech and I love it, but than I do not have rear a/c.

 

I have the rear mat, and I also have rear a/c on my 1994. Seems to fit just fine.

 

I got the factory rear mat. It's about 5 inches too wide with rear AC but unlike weathertech, it doesn't have a lip so trimming it doesn't interfere with that feature. It's also much heavier/thicker than weathertech. For the rear, it's mostly a matter of opinion. For the front and mid mats, the factory gives far better coverage. The weathertech don't even come close to comparing.
