kennygunit 10 Report post Posted May 5, 2012 Hello, I think i found a 9" rear axle housing online for my 1969 Mustang coupe, but i want to make sure it correct. I found it used for $200, and it comes with 28 spline axles (i don't need the axles though because i'm going 31 spline). Do these dimensions sound correct? about 54 1/2" housing flange to housing flange, no axles in it Center to center for the perches is about 43 3/4" Are those the right dimension and is that a good price? Thanks! Quote Share this post Link to post Share on other sites
RogerC 136 Report post Posted May 5, 2012 about 54 1/2" housing flange to housing flange, no axles in it 54 1/4" inside face of flange to inside face of flange so 54 1/2" sounds right to the outside faces. Center to center for the perches is about 43 3/4" Should be 43" for 65-78 mustangs Quote Share this post Link to post Share on other sites
