Here's the drawing from the official spec. SAE J2513. I think the slots for the pins has varied some in the past.I'm hoping someone can help with some dimensions. My plan is to fabricate a standard SSQA attachment receiver for the front of the loader. I've seen a few drawings that show widths clearly enough, but I'm struggling to find anything that isn't too blurry to read that would give dimensions 'A' and 'B' shown on my attached sketch of a section view of an attachment plate.
Can anyone point to a readable drawing ?
Many thanks, and apologies if it's right in front of me and I can't see it. Apparently it's a special skill of mine
Front loader for a B7200

Thanks for the info and the pics Chim - it's appreciated.I have three that I measured this morning. Dimension "A" is 16" and Dimension "B" is 1-1/2".
For the first project that required a plate (snow plow) the first plate had to be returned because it was just a bit short in the "A" dimension and the tabs on the Kubota's loader were longer than that. When the top of the plate was hooked on the Kubota, the bottom was held away by the bottom tabs of the plate and the round pins couldn't engage. The manufacturer (I think it was Titan, but sold through a third party) paid the shipping.
Also, the square holes in the bottom are cut square with the material, rather than parallel with the plate so that the flat part of the round pin
makes full contact.
One is a 3/8" thick plate and another is a square tube frame - both already made up that I purchased. The third is a square tube frame I made for a recent project.
Pics below are from the (purchased) snow plow plate. The 16" is with the end of my folding rule jammed into the upper bend. Sorry for the out-of-focus shot
Excellent, thanks. I had found a version of this drawing but it was so blurry that I couldn't read any of it.
I've found a couple of references that suggest the wedge pin diameter is typically 1.25". Does this sound right, or since it's dimension isn't included in the drawing, does that mean it can vary ?

As TheOldHokie said, the drawing is minimal. The slot is 2" wide, so a 1-1/4 pin would give + or - 3/8" on engagement. My implements all have a wider slot, I think, or I'm a better driver than I thought
.
Comparing the round pin diameter to the dimensions of the slot can be a little deceiving. The pin (I can measure it but think its around an inch) is sliced at an angle and when mine are fully engaged, the flat part of the angled cut is about half way through the bottom slot. The round side, opposite the flat, stands away from that side of the slot. Hope that makes sense.
Here are a few more pictures showing the engagement on the factory bucket The round pin measures 1-1/4"Ø (at least on my "Merican" tape measure, although it could be a metric part). The pins engage about half of the flat.
The one picture shows how the hole in the bucket being cut square with the material of the bucket's bottom flange mates with the angle flat of the pin. The pins have fairly heavy springs that get compressed when the levers are down. The mating angles and spring tension keep the bucket firmly attached. I wiggle the joystick between curl and dump a few times to ensure the pins are fully seated.
