Many of these backs require the removal of the GG and spring (Graflok) back for mounting. I've always rejected these. A few years ago I found a used Sinar 6x12 Zoom back, which adjusts (even in between frames) to 6x4.5, 6x6, 6x7, 6x9, & 6x12. I happen to use it as a 6x12 back only. This back inserts just like any film holder and works with 120 and 220 film.
