8.75 SNAFU

I found an 8.75 under a Chrysler Newport in the bone yard. I shortened it to fit in my Dart. I ordered axles from Strange. I find that the axles are 26 3/16" from tip to flange stop snap ring. Measuring from the thrust block to the axle flange edge is 25 11/16", adding the backing plate, 25 13/16". Am I missing something or are these axles 3/8" too long?
