eblank, I installed 4.77 gears in the front and rear diffs in my garage and it was quite easy really, and in my opinion is almost a requirement to keep the VX feeling like a VX with larger tires.

Braking and acceleration have obviously gone down slightly but it is hard to tell at all, I have been pleasantly surprised that the change from 33" tires is not more noticable. I did have a little more cladding to cut (and I hammered and cut off some more metal but that probably was not necessary) and I am very pleased with the results.
