Will the valve cover he was selling not physically bolt onto the slant six head in your car? I don't know a lot about them, but I would think an NOS chrome Direct Connection valve cover would bolt onto any slant 6 of the 70-ish era.
If the valve cover he has is for a hydraulic lifter engine and he has a solid lifter engine, then no, it won't work for him. In all these years I've never, ever seen a Mopar Performance Chrome valve cover for the hydraulic lifter slant 6. I wasn't even aware they ever made one.
