Palitoy Dengar cardback question

I'm on the lookout for a cardback to cut the nameplate out and put in my carded Palitoy Dengar. I've been looking for the exact same cardback without success, then it occured to me are there other Dengar cardbacks that have the exact same front & back. I saw a German Parker one and it looks pretty bang on. Any others you can think of? also, is there a chance that if I find a cardback, it may not have been printed front and back exactly the same as mine, therefore the name plate and figures on back won't line up?
