Dan,
You have to check what is the origanl part extrusion. If the extrusion is 7075T6511 you need to check what is the dimension of the extrusion. If you machine the part out of 7075T73 Plate you need to check the Ftu, Fty property to make sure your orignal applied load and material allowable...
Koopas,
When you calculate your SED material shear allowable the formula Pso = Fsu_mat'l*2*t*(Edge Distance-0.383*D_hole)
Edge Distance should be measure from the center of the hole to the edge of the part. This allowable is for your material shear out. If you have ED is less than 2D, you need...

The NAS1097 rivet is developed by Douglas aircraft with a reduced countersunk head. The MS20427 rivet is a larger countersunk head which can knife-edge the skin (sheet). MIL HB-5 provide the bearing/shear failure of the joint strength. MIL HB-5H (Latest J) table...
