Hey Greg, thanks for reaching out!
It sounds like you're looking for the 10" Dexter Electric Trailer Brakes # K23-462-463-00 which are rated for 4.4K axles and have a bolt pattern of 2-7/8" at the top and 3-1/4" at the bottom (see attached photo). If you wanted to upgrade to the Nev-R-Adjust kit then you can use the part # K23-478-479 instead.
If you have a different bolt pattern than what is shown, please let me know and I'll be more than happy to help you figure out what you're needing!
