Oil pan still leaking

[JAM1777]

I just had my rear main seal changed and transmission serviced with new gasket and filter because of all the leaks it had. And put new oil pan gasket and it still leaked. Found out pan was warped so had a friend fix the warped pan and put it back on and its still leaking. Im frustrated now and wondering if i should just get a new oil pan?? And if yes , does anyone know of a good place to order one? Something decent that will help with cooling? Or just something standard is ok. Any help would be appreciated. Its a 1969 C10 longbed. 350 smallblock 4 bolt main with a turbo 350 tranny. Once again thanks for any help
