‘37 -‘39 steering box wanna-be

[ford38v8]

A friend has a ‘38 steering box to install in his ‘36, but has only the ‘36 mounting bracket that must be drilled, or is it his frame to be drilled? Can anyone provide exact locations for the mounting holes? I know it can be done hit and miss, but that’s not going to pass muster for this job, his engine is in, and he’d rather put the ‘36 box back in than to remove the engine, if that’s required to do it right. I’ve never had the pleasure, so I’m way out in left field with anything I’d tell him. Thanks in advance!
