The 98 spec Glanza units and different to the 96 spec units. To fit the 98 spec lenses to the 96 spec units, you have to modify them and bond them on instead of screwing them on. And if you whack the new lenses on to the old clusters, they do look a bit crap tbh. As for the Reflets, the full units look tidier than just the lenses. If I had the choice again, I'd buy full Reflet units for mine instead of bonding the lenses on the stock units! Full units ftw!
