No, the old Fitchel & Sachs racing clutch was used on racing Alfa TZ's, TI Supers and GTA's, as well as many others. There were several versions, or variations, including a "lightweight" version for TZ's that was usually quickly replaced by the heavier GTA version, as the light one did not hold up well.
These were often used with solid hub discs, also from F & S. These are no longer available new, though there is an Asian copy that is not as good as originals. I've run these for many years, and used to rebuild them for pure race use.
I've a few of these that are not for sale for my own use. I too am almost 20 years older than my 52 year old Ausca spider, and these easily hold the power of my GTA engine without excessive pedal effort.
Early versions had a flat ring welded to the top of the spring covers. Later, about '66, the big ring was thinned a bit, but has a rounded lip, so it is as stiff or stiffer. The light TZ version had a thinner base plate that bolted to the flywheel, and you KNEW it was thinner because bolted up to the flywheel, this plate sometimes was wavy (!!!) with heavy springs installed.
I'll try posting some pictures, but other BB members tell me photo posting was not working earlier today.
If my photos don't work here, (Still NOT working now!) send me a PM with your e-mail address and I'll send them by e-mail.
