Most Compact 3/8" Impact Wrench Ever??!? DeWalt DCF850 Frankenstein

This was in pursuit of a really compact, but still somewhat useful impact wrench. I use sockets a hundred times more than I use bits, and I've always loved compact tools because they are just easier to work with. So I bought the stubbiest quality impact driver on the market, the DeWalt DCF850. Then I ordered up a standard 3/8 anvil that fits a number of DeWalt tools. (Part Number 608116-00SV) Then, I tore apart my brand new impact driver and replaced the driver collet with the 3/8 anvil. Total length from the back of the tool to the seat of the anvil (where the socket bottoms out on the anvil) is less than four inches. Now, I have this little monster, and it fits just about anywhere.
