Hey Stan - My SM had a Charlyn PS installed when I acquired it. It's hood had been modified slightly (beat out) to make room for the steering motor. In the photo you can see the bump - it's to the right of the hood centerline, ahead of the temperature gage.
I also have an SH w/o power steering. It's hood is noticably smaller than the SM's. So gotta presume a more drastic modification would be required on the SH tin to get the hood to fit over a steering motor. I've never seen a Charlynn kit installed on an H or SH, but I'm sure someone out there has done it and can offer advice.
Good luck!! Bob M
