Seems the 105 series they couldnt be bothered cutting the centre part out of the box. I had to do that myself then viola they both went in perfect.What I found behind the glove box in my 1999 UZJ100 was exactly what was shown on the YouTube video I mentioned (which was about replacing an existing, dirty cabin air filter.) The housing accepted the 2 cabin air filter elements supplied by Denso without issue.
One day I will understand what models have what (maybe lol)
