I have a spring back Miniature Pacemaker Speed Graphic. So far, I love it. However, I am currently using an Adapt-A-Roll....which I am NOT loving. I'd like to convert to a Graflok. However, I am having a really difficult time finding a back. However, I was wondering...are all 2x3 (6x9...?) Graflok backs the same? Meaning, could one meant for an XL be modified to work in a Mini Graphic? I don't want to permanently mount a roll back as I would like to use the various b&w sheet film sometime. But, I've had a hard time with the AAR620---sometimes the "clicker" doesn't work, or I jam while loading, etc.

Thoughts?

There was a Graflok made to retrofit Anniversary Speeds and likely the Miniature Speeds also. A Graflok for a Pacemaker has its mount holes at a different position than the Anny/Miniature. They are about 1/2 - 3/4 the mount screw diameter off set therefore the mount holes will have to be elongated to work.

I have not worked with an XL so I don't know if the XL Graflok will fit or not.
It likely will not fit as the bodies are different shape even though the format is the same.

That is good to know...I didn't realize a Mini/Anni (which I have also with a spring back) had a different back than a Pacemaker. I guess that narrows it down even more Maybe I will just end up getting super efficient with my AAR620, haha.
