Fuse prongs missing in fuse box

Prongs missing in fuse box for 2011 Express

per GM there are different fuse boxes depending on the options the vehicle has, the wires are in the bottom of the fuse box in most cases , the Fuse box must be changed, est for my 2500 series express van was $200. watching the junk ward for the right truck.

Some spots are blanks. You can use a piggy back fuse to add a circuit.
