Got "something stuck" in the gas tank need suggestion on getting it out.

[Mxracer202]

Ok so I was pulling the gass tank out of my c10 and since iIdont have the keys to pop off the locking cap (already frustrated) I took a flat head and started prying it to try and bend it enough where it would just pop out. But it of course is made of aluminun and just snapped off falling in the tank along with my screw driver! AHHHH!! bad idea. so now ive pulled my tank and it wont come out I measured the other hole, then one where the fuel pump goes into the tank, same size. The only thing I can really think of is drilling out the key hole and thinking, hoping, it will come out peacefully! I dont want to cut into the tank or buy a new one so any suggestions??????
