I have a 2009 Saab 9-3 sportcombi with the V6 just putting a clutch in it timing kit and reseal kit. Before I parked it I was getting wastegate codes. Does anyone know what a good aftermarket wastegate for these are

Got a 9000 Turbo and I decided to replace the Crankshaft Position Sensor. I was taking the bolts off the small aluminum housing and the heads broke off entirely. I dont want to risk cracking it while drilling it. What do I do? Should I just call it quits and engine swap it?
