For your information and for future customer notice, I have received and installed the ordered ARAX screens on my Hasselblad (this you know it works) and on my YASHICA MAT 124G (just need a little grinding). It is ok, the only challenge is to adjust with wedges to keep the focusing plan as with original screen.
