Default Cabriolet engine mount question

My 77 3.2 conversion came with an engine mount that has a "shock absorber" integrated into it to allow some torque movement. I was told this type of mount is unique to cabs. Does anyone know if this is true and if so, what is its purpose and are there any advantages or disadvantages to using it in a 77 coupe?

It is definitey true and allthe parts diagrams show it for cabs. Not sure of the purpose though , may have something to do with stopping the body from flexing from the torque as it is not as rigid, but that would be a big *** guess.

You are correct, they are exclusive to cabs. The strut is to minimize vibration. It also has a a central round rubber mount with three bolts as an additional isolator. So you have the traditional mounts at the ends of the bar, the central rubber mount and the strut all just for the cab. In a coupe you may not know the engine is running with all that insulation :-)

Google 'Porsche PET' select '911' then '87-89' Page 73 shows the coupe vs the cab mount side by side. Just FYI - great resource.
