Swing arm length

What is the length of a S/A swing arm. (C/L of swing arm pivot to axle C/L) ?
I'm building a "soft tail" Bonneville bobber and may utilize a S/A swing arm.
Bonneville's are 19", 482 mm...
Chooglin' two '05 Bonnie's…
Goodwood Green 73 RWHP Soft Tail Bobber…
BB Cafe Racer…

I make mine 22", although the axle position is a variable. The width may be an issue.

I see it as:

~21.5" C/L of the pivot to C/L of axle slid all the way forward.
~11.25" wide ID between the frame at the pivot point, with some room to play with spacers on the left (this is my least confident measurement as I'm not willing to pop the chain guard off unless requested ...maybe +/- .25").
~10.375" ID between the axle plates.
