Chujo - Powers Up!

As much as I like this cel, I'm beginning to question its authenticity and my sanity. I could swear that I've seen the scene this cel is from.
Vividly, fully animated in my mind, But it could just be that I've seen GR so many times that I'm starting to make stuff up. I've gone through the JP and US DVDs and could not find a corresponding screenshot. Maybe it was originally on the VHS/LD release but cut for the DVD...
