I meant that Eric should post pictures.

squeeze Yes, I know all about the oil leak issue, and I never meant to imply that you were wrong, when I read your earlier post I thought you said that the block in your truck didn't have provisions for side mounts, but apparently you meant the frame had no provision. That's why I said you must have a '57 block. As far as what years did or didn't tap that hole, I don't really know and I'm not too worried about it.
