Can anyone recommend a good trans pan for 727 with a drain plug? I would love to find a cast one, but can't find anything that isn't deeper, and I don't want it hanging any lower.

I bought a thick steel, can't remember the brand, years ago, but put it in storage shortly after. I've had leak problems ever since, and yes it'sthe pan. It's 3/16" and nearly impossible for me to get it flat. I've tried all the gaskets including the reusable 46re.
