So I just bought a replacement back for my Speed Graphic, and it came with Groundglass significantly more scratched up than my older piece. Here's the problem. The older piece came with a frensel, the new one did not. Can I use the Frensel with the older piece in the new back? It looks like the older one is the "Grafloc (with the two metal arms)" while my new one is the "Graphic back" (no metal arms, just black springy things)... Any thoughts?
