Can you take a pic of your J2 Bracket? I'm not totally expert on all the iterations - the calcs above are based on being able to use the clamp bolt as a pad bolt. If that is not an option with your bracket I think it adds 37mm to the minimum width.
See pix below. The blind holes are the more inner holes on the underside of the bracket.

What is your extension tilt angle?
Current tilt is 7 degrees.

The race cups came about as a nicer solution than the aluminium pipe I used to slice and grind. 84mm ID for skinny cyclists, 100mm for me.
There are 5mm and 10mm pads for the cups to fine tune the fit. I am fine with the 5mm pads (as seen here, I am no waif) - the cups were in fact designed with my arms as the maximum size to fit.
No need to scale web photos - I'm happy to help.
Thanks, again.

I would add that you'll likely find it easier to relax into a tight position with the Race cups but that the same c-c measurement on Race as F19 will feel a lot tighter. So try to measure to where you actually place your elbows on the F19, then set up race to match. The Race cups allow no ambiguity about elbow position.That's a really good point. I looked at the indentions in the pad this morning. My elbows rest in the wider crease of the F-19 pads (more or less), where the cup actually turns "up". That puts my effective Z more at about 260mm or so. That would mean my "tested Z" was more like 200mm vice the 157mm c-c measurement. Since the F19 is pretty sloppy, there's probably a good bit of variation from one day to the next.
ETA: I meant to ask, where are you located in NZ? I used to spend a fair amount of time over there working for the RNZ(ed)AF, as the chief engineer for the P-3K2. You may occasionally see it flying around...
