Font clip body panels???

[boygenius]

OK here is the story. I have a RUSTY spare tire well. I ordered a front clip from the gas tank foward but I no longer want to replace the entire front end. I am afraid of welding in the clip at an angle and having a crooked looking car. The rest of the metal is in OK shape and can be repaired with a few metal patches without risking mis-aligning the front of the car. My question is this, can I drill out the welds of the new front clip to remove the front and bottom piece to weld onto my car without destroying the new part. I figure that I could only sell the front clip for what I would have to pay for the two maybe three repair panels so whats the point of paying all those shipping charges. Thank you...
