8-3/4 brake gap/ standoff odd measurement

Hey guys. I searched this question front to back but here it goes. A body 8-3/4 I’m measuring 2” brake stand off from face of bearing end to axle face.. I’m ordering new axles and moser has never heard of a stand-off like that.. was a small bolt pattern axle. Any input on this? Thanks E6D8DC96-48E6-414F-8B0B-E7FC7DAEB19E.jpeg
