Hi Jerry, Can you post a picture that shows an example or two of an "adjustable strut". As pictured, it looks like there would still be quite a bit of weight on the rear of the engine, so the strut can't just be a trivial piece. Goodness knows that if this evolved on the other list, it's been engineered way beyond my tolerance, but I just can't quite picture what you have in mind for the rear support. Doesn't Atkins also use a beam system like this? I seem to recall that he used to sell the beams, but you were on your own to make the mount. Could be wrong about that.
