Posting this in a separate thread, so the original thread would be not contaminated with my newbie confusions.
And perhaps, it will hopefully help someone else.
Oh wow!
I actually found out what you were talking about!
Heh, sorry but this just does not seem very obvious as springing out the back.
At least not to me.
First I removed the GG frame portion, and fitted a holder.
BTW, I have the entire back of mine oriented in portrait orientation, so it, the GG frame portion, slides upwards.
Heh, I actually, "discovered" the landscape/portrait orientation playing w/ the camera previously.
So now, I have the GG frame portion removed, and amazingly, a holder fits perfectly.
Cool, it fits, but what holds it in place?
Ahh, look, what do these sliding tabs do? Woo, it clips into the holder, holding it!
Duh, I feel soo stoopid...
Thanks for the info!
Another stoopid question:
With the GG frame portion off, it's what is called a Graflock back?
I use a PA-45 in my Sinar F2 all the time with no issue. You push in the two chrome spring clips above and below the ground glass and slide the ground-glass frame sideways. It comes unclipped and will come off the camera in your hand. Then, place the PA-45 in its place, making sure the ridge to the right of the opening seats in the slot on the camera, the same way any film holder would do. Then, slide the two tabs at the top and bottom of the back so that they slide into slots at the edges of the PA-45 and lock it in place.
The Graflok design includes the ground-glass frame held on with spring clips, and the two tabs to lock into those slots. The "standard" only requires that the tabs be positioned in a particular way.
Note that the Graflok tabs must be open for the ground glass frame to seat properly.

Hmm, I just bought a Fuji PA-45 back.
I have some FP100C45 film on the way.
I have test mounted this back in front of the ground glass, by opening/extending the back by use of the two levers, one on each side.
I am assuming this is how you would mount 4x5 double sided sheet film holders as well.
Is this incorrect?
I'm confused about the Graflock part above, and attaching this in lieu of the GG ?
I am working from "instructions" found here:
<<http://www.webster.edu/acadaffairs/asp/mediacenter/Photo/equipment%20manuals/sinar_introduction_manual.pdf>>
I will take some pics tonight.
Yeap, sure is confusing.
I have taken the back completely off, and apart.
Though, I have not tried to take the GG off while the back is still on.
I will look at this tonight.
Any problems with the method of putting the film holders in front of the ground glass?
For holders that don't have protrusions that will bear on the glass directly, and if the spring arrangement of the ground-glass holder has sufficient travel to accommodate the thickness of the back, then there's nothing wrong with just sliding it under the ground glass. I do not know whether the back on the Sinar will accommodate a Polaroid 405, aside from the issue described by the OP. It will absolutely accommodate a Fuji PA-45 in that way, though not with an abundance of margin. I just tested it. The PA-45 back is about 1.07" thick.
