I'm doing the shelby drop and cleaning up the wheel well to install my new opentracker control arms. I guess when the car was new, someone went crazy with the rubberized undercoating and absolutely flooded the pan in the shock tower under where the control arms mount. I chipped out chunks 3/8" thick. No real rust damage, just some surface rust I should be able to take care of with some rust converter/encapsulator. My question is, should there be a drain somewhere in that pan? Seems like it would, but I haven't found one yet.
