Not positive about this, but I think the F57 is the 95-96 version of the 4405 and the F77 is the 97 version of the 4405. I think that you need to check out the front output to see if it will work because the 97 has a CV front driveshaft and the 95-96 doesn't IIRC.

I know that other people have used the 98+ version in place of the 97, but the issue there is that the 98+ uses the ABS sensor on the rear axle for the VSS (vehicle speed sensor) but on the 97 the VSS is mounted in the Transfer Case. People have gotten around this by using the rear case from the 97 with the front case and guts of the 98+.

Hope that helps. I think that Izwack has torn a couple of these apart, so he may be able to help you better.

Here is a thread with some good pics and a discussion of differences between various versions of the 4405.:
