Replacement 12 inch by 2 inch Brake Assemblies for 6k Axle that Use 4 Bolt Mounting Pattern

Question:

Hi, I have a Kiefer Built horse trailer with a HammerBlow Corp. axle. The nameplate on the axle reads 6000lb rated, and it has 12x2inch brakes. The drum is a 6 on 5 1/2inch bolt pattern, and the axle has the 4-bolt mount. The backer plate measures the same as a few other replies I read in the QandA section, 3.125inch on top, 2.5on bottom, and 3.375inch between top and bottom holes. The center hole is 3 17/32inch just under 3 9/16. The only reason I am asking this is I havent read that dimension in any other posts, and I want to make sure that these will fit my application before ordering. I believe the 5-bolt backers have a center dimension of 3 8/32inch just over 3 1/4, which is too small for this axle.
