Not to argue, but those numbers don't jive with actual shipping weights kennyw posted, 475, nor the combined D60/14FF weight someone else posted, of 800lbs. With a bit more searching, there are at least two other people that came up with 475# for the rear. With drums to boot.
14SF has got to be quite a bit lighter than the 14FF, with no hubs, no monster drums, and probably lighter axleshafts. It's not fun to move around, but it can be done with two people by hand, and it's not overly painful. I used an engine hoist to move the 14FF I had. I'd say a good 100lbs less than the 14FF. I just did a quick search, didn't find an actual 14SF weight though.
