I was a bit confused with the identifications in my initial post. Did some additional research and what I'm looking for is a casting with a 14WA stamping on it and ~12mm holes for mounting vs the newer 14WB which increased the mounting bolt size to 14mm.
The 14WH is actually the stock caliper on 4th gen limited/sport and the 14WG is what is stock on my 4th gen SR5. I'm looking to do a brake swap for both upgraded rotor size and piston diameter. Just found
this post with a wealth of information if you wanted to know more.
