I am using the CE Inc Biscuts on our Anglia (dad fabbed the brackets). We chose them as the engien is a (hack cough, mumble) V 6 and the engine compartment is very tight (shaped like a funnel). We have found these to be exceptionally stiff (as they are basically rbeer molded over a metal insert) yet they do damp out most vibration from a short crank (4 main bearing V) SOHC 6.
Hope that helps, I'll see about pictures.
