LOL.
Thats what I did. Had the car on jackstands, put the differential on the floor jack and slid it under my car. Then I lifted it up to get the rear bolt in place and held up the front while I screwed in the mount bolts. Wish I had more room and more hands, but I got it done.
Make sure you loosen up the sway bar bushing mounts. You'll need the clearance.

I drove my car on a 100 mile round trip to my sisters and reset the gas mileage. I kept it around 75 MPH. I noticed that I never needed the engine to kick down in gear while I was driving where it would have kicked down before. Also, gas mileage was about 25-26 mpg the whole way. It was mountainous terrain...lots of big up and downs.

good, so your mpg hasnt changed much either...
many ppl think thats a drawback to this mod - but my mpg is a sh!tty as its always been - your apparently hasn't changed (much if any) and most others don't report meaningful loss...
going form 3.5 to 3.9 or 4.0 might be different - buy 3.3 to 3.5 or 3.7 hasnt shown to be detrimental to mpg
This of course does not count the super sh!tty mpg from staying in 2nd & 3rd and driving spirited more often because its fun

recent road trip averaging 70mph I got as good as I ever got...
even under typical circumstances (street & freeway) I never saw more than 1mpg difference... but most of my driving is not typical.
In normal driving its not likely that anyone is going to see a significant decrease in mpg by switching form 3.3 to 3.5 or 3.7
