69 xr7 9 inch rear end

Are all cougar 9 inch rears large or small bearing? Just curious to see if I need to measure before ordering from MustangSteve.:uhoh:

They are available both ways and generally small block cars got the small bearing unit and big block cars the big unit. Small usually has 28 spline axles (and the end of the axle flange has a recess) and the big 31 spline (and the end of the axle flange is flat with two holes).

Thanks.

Since mine is a 351 4V I will assume I have the small bearings.
