Start with X=0, Y=0 and adjust width/height to crop from the right and bottom.
To crop equal margins on all sides, add the margin to X and Y and subtract 2× from width and height.
Use GifMash's GIF Info tool first to see the exact dimensions.

Can I crop an animated GIF without breaking the animation?

Yes. GifMash applies the crop to every frame simultaneously, so the animation remains intact.

Does cropping reduce GIF file size?

Yes — removing pixels directly reduces the amount of data per frame, which reduces file size.
