Moser axle brake pilot
 

Here is a picture of the add on spacer to make the Moser axles the correct pilot length as the factory 79-81 rear disc axles to locate a hubcentric wheel. The Moser pilot was actually 0.030 smaller than factory also.

For those interested the factory 28 spline axles in a Eaton 28 spline posi only 1 had a slight twist after lots of launches with slicks and a bunch of 1.50s 60 fts.

Looks good.
