On the documentation with my SD-38, the diagrams show the locations of the hooks, a bit of squeezing and rocking works, squeeze so your kind of pinching between the shell and frame for leverage, still isn;t anywhere near as hard as my Athearn BB 440's, broke the first one.
Well I tried squeezing as hard as I could at the rear hook location on the shell to no avail.
Couldn't see how any amount of squeezing on the cab was going to work, I finally resorted to a really thin chisel Xacto blade to reach under the cab and get the front hooks and then very carefully used it on the rear as well. With care and a little additional squeezing and rocking they all released (no harm done) and we are operational with a decoder. Now to redo the handrails and couplers.
I like the Kato light pipes and having no connection to the shell from the frame.
