Yes. But only if we're talking about a 10" SBP drum system migrating from an SBP 7¼" to an SBP 8.75" rear axle, then the only fly in the ointment appears to be the support (backing plate). More important than the 4 hole/5 hole mounting bolts, is the fact that the support for a 7¼" is setup for a 2.75" axle tube, where as 8¼ thru Dana 60 use a 3" tube. (Yes the Dana 60 axle tubes leave the housing at 4" but are stepped down to 3" by the time a clip (U-bolt) is used on them.)
