Sorry...it's another spare wheel question :-\

I need to get a spare wheel for an imminent road trip (yep...I forgot all about it and now it's a rush job 🙄) so I've been having a poke around on here and online and now I'm a little confused.

I have a '67 vRS 245 that has 225/35-R19 tyres and I'm trying to determine what size spare wheel to get. I did try a full size a while back but it pushed the boot floor up so just going to go for a space saver. What I'm wondering is what size space saver to go for...would this fit the bill?

Thanks...
