standoff spacers for bolting later crankcase?

[Martin Prior]

Rubber mounts were fitted to engines for high and low frame chassis, but the engine mountings are set lower on engines intended for low-frame chassis. I think that Jon's problem is that he has a low frame crankcase in a high frame chassis and it's already sitting considerably higher than it should. The rubber mounts will make this worse, but even without them, the line of the drivetrain is likely to cause other problems.
