standoff spacers for bolting later crankcase?

Until last week, my short wheelbase Ulster was fitted with a later, rubber foot, engine. It used the standard rubber foot kit without any issues.

Thanks all. 
I can see that geometry probably makes the SWB chassis more extreme than a LWB high chassis, but this is good enough for me!

I'd be interested to know what the actual difference in height between rubber mounting and "without" makes, (1/8"??) as I see the lower rubber is partially recessed. 

Do all use the bottom rubber onto the large flat washer, or is that just extra height... if the surface of the chassis rail is good?
