Maybe someone can give me a hand. O K so here is the issue, I have a 69 LWB that I converted to a SWB, The stock frame had leaf springs and I dont have a bed. The issue is that I bought a notch from SD but where the notch sits flat on the frame to rear end looks to far forward. I want to install the notched but im afraid that the rear end will hit the front of the notch when the rear end travels up ( and the rear tire not be centered ). This night be because im switching to a Ford 9" and it is set onto the leafs but something might be off. Can someone give me a measurement from the end of the frame ( tail area ) to the center line of the axle on both sides? this way it solves 2 issues the C-notch issue and the location to mount my four link. thanks in advance...

Actually I think I may have found the answer. the CL of the rear axle is 7.5 inched from the back or the oval on the frame. if this sounds correct please let me know. Thanks.
