Hello so I have taken on a new project, I have learned a lot from all you guys and have rebuilt a 292 from the crank up and it runs and sounds sweet. I have now moved on to the body restoration and need to replace the inner and outer rockers both sides. I started drilling out spot welds and god there must be a million . Does anyone have a trick for locating and drilling them out. The welds towards the front seem to be the worse  it started to rain so I was able to pack my stuff up and Leave them for tomorrow. Thanks for any ideas .
