Correct Oil Pan Identification for '65 273 in Valiant/Barracuda?

Use the thick early brick mounts and you can get away with a stock chrome pan with a small ding if any. I had a 340 and a 360 chrome pan clear with the brick mounts. But a Mr Gasket 360 chrome pan would not clear a M72 -HV oil pump.....? Other one did without issue.
