I’m definitely interested to see how it goes once you’re all buttoned up with it best of luck and can’t wait to hear the results.
I've got a set of front and rears off a 4.4L - they're 3.64 ratio. Fronts are a direct swap. On the rears, you have to pop out the stub axles from your stock 4.10 diff and move them over to the 3.64 donor diff. It takes all of 5 minutes, and you should be replacing the seals while you have it out anyway (which requires removing the stub axles).

I've got high hopes for the conversion because 1st gear is just crazy short, even for towing, and as you know, 5th is a screamer on the highway. With headers and EU2 tune, I believe I'm ~10% up on power, so the 11% taller final drive gearing should be, well, perfect!
