yay! we got the rock out!....thanx to my buddy's dad and his friends on the street...we hit it w/ some mapp gas torchin, and an impact wrench and went to town....turns out i only have 3 good holes to thread new screws in....the 4th hole we tried to drill out the threaded shank after breaking off the screw head then we tried to tap it but ended up breaking the tap...im sure 3 really tight screws will hold that intake grate on fine dont you guys think?.....the rock came out after a minute of loosening it from the impellar w/ a mini pry bar and no damage to the impellar! im so glad we didnt have to pull the pump off that would be horrible! thanx to errbody on here for their advice...
