Any different internal parts from the RT Valve and Classic Valve?

I was looking at the diagram from the RT Valve and Classic Valve, the internals looked the same from each other besides the on/off assemblys, so I was thinking, if its possible, if I use an RT Valve on/off assembly in my Classic Valve, will it do anything? or is it not even possible?

Will not work. There are more differences than that. That's why everyone who want's to upgrade to RT has to buy a new valve. There is an extra milled channel with new internals inside it that give you the RT feel and high recharge rate.

The on/off assembly from a retro valve will fit and work in a classic valve. Just make sure you use the top two o-rings from the classic valve instead of the ones from the retro assembly.
