Marvin, Layne's Louvres are what's on my car. They were made slightly "off" from the works style, because he intended them to work WITH the spears.
The engine with the broken crankshaft should be 100% original BMC. ther than taking the oil pan off to see WTF happened, it wasn't torn down to build the engine that was in the car at the time of the wreck.
That engine is the example I cite when encouraging people here to get their dampers inspected, rebuilt or replaced! Interesting tidbit: his crank damper came apart like one (1) residential block from his house, then in Lafayette, Louisiana (off Johnson St, towards The Mall, for Jim's benefit

) and he immediately shut the engine down as soon as he felt the vibration starting__this at 18 - 20 MPH. And it probably won't take much to convince you that Layne normally (and likely just beforehand) drove like a madman. This happened in about October 1987, on his way home from visiting me in Lafayette General, where they had just removed my gall bladder__the old fashioned way, through my stomach. His then wife (coincidentally, today is HER birthday) volunteered to drive me back a week or so later to have the stitches removed, as my then wife was working in another hospital.
So the synapsis is: the engine with the broken crank should be the color it was painted at the factory; the engine in the car Layne flipped is the one I built and painted Onan Green; Layne and his ex now have a grandson and I still communicate with both. Small world, eh?
