I am not sure what it is out of but its going in a scamp with a 440 and a 4 speed that should run low 11's or high 10's. Are these axles going to hold up?

Stick shift and 30 stock type 30 spline axles equals future breakage Been there, done that, even a hard leaving automatic car will break the 30 spline ends off in the splines of the spool or posi Mr.Cab Racing and winning with Mopars since 1964.

I've never seen them in a Ford 3/4 ton Dana 60, the first one I saw was in Dana 60 out of a 1969 or 1970 3/4 ton Chevy or GMC pickup The last set of 30 spline axles I saw was in a late model(1970 or later) Dana 60 HD out of a Dodge or Ford ( CRS, ) class C motorthome chassis Mr.Cab Racing and winning with Mopars since 1964.

What is different about the truck vs. the 30 spline in an 8.75 ? The end of the axles are different All kidding aside 8 3/4 axles will fit the 30 spline posi perfectly if your cutting a truck Dana down to fit in a B body As far as using stock 8 3/4 axles in a 4 speed OP, buy the 35 spline conversion kit from Cass at Dr Diff and make that posi a 35 spline,a new set of axles are needed anyways so buy the best size That will be money well spent Mr.Cab Racing and winning with Mopars since 1964.

The Dana 60 30 spline that I built for my Polara came from an International Travelall. For serious abuse step up to the 35 spline axles and the PowerLock carrier for street or a spool for the strip.
