It will bolt right in, but I'm not sure on driveshaft length.  The 8.25" may have a longer pinion than the D35, so your stock driveshaft may be too long.  They are easy to have a driveline shop shorten.
I'd install it, then measure for the driveshaft and have it cut down if necessary.  If you install too long a driveshaft, it could crack the transfer case.
Good swap, the 8.25" is a great axle.
