Sounds good that there are those who want to do these conversions. It takes some time, but once you dive in, it really is straight forward. Will post pics on my next conversion which I will be starting tonight. So far I've done my SD70ACes, ES44's and AC4400's. Next up are the AC6000's, SD40-2's, and Dash-8 narrow nose engines. I use the new Kadee 745's on everything, which gives you the metal coupler (springs hidden) and plastic draft boxes. These are very nice couplers.
