I have a Kevko pan on my small block Australian A body and it fitted great with no leaks but was about an inch lower than the crossmember so I just welded a piece on the lower section of the crossmember that was just below the pan so if I ever bottomed out on something it would only hit the K member and not take out the pan.
Yeah, I agree on the skid plate idea, especially if the car is lowered. When I looked last, a couple years ago, there were a couple of aftermarket plates available on the internet.
