What Spectrasonics plugs work in PT 7.4 (Leopard)

I'm still in the stone age with Spectrasonics Atmosphere, Trilogy, and RMX running beautifully in PT HD 7.1 on a Mac G5 2.0ghz Tiger 10.4.6. This system is rock solid and I want to keep it this way.

I am installing a second drive with Leopard 10.5.6 and upgrading to PT 7.4.3 I will not go to 8.0 on my G5 Mac b/c of plug-in incompatibilities and lack of CPU horsepower.

Will Leopard PT 7.4.3 run Atmosphere, Trilogy, and RMX? Do I need to install a "wrapper"? If so, how do I get it?

Thanks for any and all help.
