Lookin' good! Can't go wrong with a Qp Rear. I have one in my wagon. If it were me and I had overdrive I would go with the 3:73. I do not have overdrive and I went with 3:25. You can order in custom width for the same price and eliminate the wheel spacers as well.
Garage looks nice! I've been to Europe once (Rome, Italy) and that's what I noticed most about construction of buildings over there. You guys build stuff to last forever! In the U.S. almost everything is "stick" built. We use a lot more wood. What are those block made of?
