Resizing a gif.

Can someone resize this gif for me.

I want it to be the size of this gif below but Im not sure the exact size.







So for clarification I want you to make the 2nd gif the same size as the first. If you could do that, it would be great. Maybe a little smaller If you want.

The sizes are:
The car thing is 478 x 218
The dancing one is 506 x 350

I'm not sure on resizing .gifs
Never worked with them before, sorry :'(

I've never ever re-sized a .gif O.O.
Sorry pal.
