E-trim HS on manual trim RV-7?

[MK77]

Hi all, I have an issue with the horizontal stabilizer on my project and need to replace it. I found a HS for sale but it was built for electric trim. My plane is set up for manual trim. As far as I can tell, the only difference between electric and manual trim as far as the HS is the hole in the spar web for the cable to pass thru which I can easily add. Anything I'm missing?

Thanks,
Matt

You aren't missing anything. There is a hole in the forward spar, a hole in the rear spar, and the hole in the elevator spar.

Of course, I assume you have the longer control horn on the trim tab already.

Yea, keeping the same elevators / trim tab which is set up for the manual trim.
