The IRS frame needed to be shortened 2.0" but the 2.0" could not come from the middle of the frame because of the differential mounting bolts. Here a few pictures of the K frame to better illustrate the cuts. The first picture is looking at the IRS frame from behind. The cut is a 1" slice that was taken from the right side, just outside of the right differential mounting bolt. A 1" slice was also taken out of the forward bar of the IRS frame (not pictured)



The next two pictures are also taken from the back side of the IRS frame. The first picture is the passenger side where a 1.0" vertical cut was made to both bars of the IRS frame.



This picture shows the "Z" shaped cut on the driver's side-just outside of the left differential mounting bolt. On the driver's side a straight 1" slice was not possible duet to the contours of the IRS frame and the left side differential bolt bushing.



This is not the differential Ill be using. I plan to use a limited slip 3.91 Getrag differential
