Early A833 4 speed linkage adjustment help

First off, I have it adjusted and working fine, so there's that, but I've come to understand that while the shifters are all "basically the same", many variations have been made over the years that do have significant differences when it comes to adjusting them. As several have mentioned the reverse lever had no hole to index to from '64 to '69 or so, but the very early shifter, like I have in my '65 project, the reverse lever is not the same width as the other two levers. My 1-2 and 3-4 levers measure about 1.25" wide, while the reverse measures about .884" wide. So, what do you index the reverse lever to? The front of the other two or the rear? Middle? Setting 1-4 levers using the 1/4" drill in the hole, and using Toolman's suggestion to engage the R lever on the transmission and then move the shifter to reverse then setting the rod, worked. This picture shows the R lever with the other two behind it, you can see the width difference. It appears that the R lever aligns with the rear of the other two, at least that's how it ended up on mine. Matching flats of the three shifter levers front and back not possible due to width differences. No hard index without special tool, or knowing to line up the rears of all three.
