Mike,
I an glad to see you found the correct Shaper Fence.
If you checked out the link br549 provided in a previous post you should have found two PDF's in my post. Scroll up from where the link takes you to that post. One has a picture of many of the Arbors from over the years and the other is a listing of the Arbors with additional information. The pictures below are more complete than the one in the PDF. Use these pictures as a reference to the PDF with the listing of the Arbors. These pictures do not include the Shaper Spindles, Router Chucks or SawSmith Arbors.

There was an error in the labeling of 12 031 and 22 031 in previous postings of the above picture. Anyone having saved it should replace it with this one.

The picture below shows the Lower Blade Guard you are using on my Model 10ER. Notice I have the saw blade on an earlier version of the 5/8" Arbor with a machined washer first followed by the blade and than the machined spacer. My Lower Blade Guard does not have the aluminum spacer in this instance. That Arbor P/N 12 031 has a shorter, by 1/8", base length than the 5/8" Universal or Molder/Dado Arbor P/N 505506 you are using. With the spacing of the quill/spindle differences of the Model 10ER and the Mark VII you may still need the spacer in the Lower Blade Guard if using the 5/8" Universal Arbor for saw blades. All that being said you could still get a 5/8" Saw Blade Arbor P/N 555321 for use on your Mark VII. It may still need to have the spacer in the lower guard depending on where the blade is positioned in the guard by the arbor. The 1-1/4" Arbor P/N 505511 puts the blade 1-1/4" out from the base end of the arbor. The 5/8" Arbor P/N 555321 puts the blade 1-1/2" out from the base end of the arbor. The 5/8" Universal Arbor P/N 505506 puts the blade 1-11/16" out from the base end of the arbor with the machined washer first. All three of these arbors, which are for use on the Mark 5 aka Mark V 500, will put the blade at different positions relative to the quill end.

Mike, I will tell you I have never owned a 1960's Mark VII so I can only go on what I have learned about them. Others who own them can give more specific information about their differences compared to a Mark 5. I do know a lot about Shopsmith Arbors.
I hope we haven't overloaded you with too much information.
