clutch kit

anyone heard of these lads, TORQUE. here's one of their products;

hey lads and lasses.. just a quick one; took out my clutch kit for routine inspection and found that it had a different 'stamp' on the pressure plate springs compared to another i had that came off a different glanza. wanted to find out if the '3H' and '3F' mean anything, perhaps the 'stiffness'...

just curious, are there any black-&-white differences between the -FE and -FTE clutch kits..? i know the release bearings can work either way in either setup. what i wanted confirmation on is if one was to use a -FE clutch kit on a -FTE setup, would there be any detrimental drawbacks to this...
