dream '94 Z28

When I bought my '98 Z28 a few weeks back the guy gave me 2 new McCleod clutches he never put in (he had heard these cars have weak clutches but never had a problem after 32K miles). I'm thinking of selling both clutches for the money to pay off my cards which I loaded up with purchases for my '94Z (the '98 wasn't planned purchase).

I called McLoed and they told me that if I have the flange style clutch I need to return it to get a 3 finger style replacement. I'm pretty sure I have the flange style, but since I don't know a whole lot about clutches, I'm not 100%. Does anyone have a pic of the 3 finger sytyle clutch?

My second question, should I keep one or sell both? The car only has 32K miles on it, and outside of regular autocrossing (once, maybe twice a month), it's my daily summer driver, and I don't thrash my cars at all (my '94 had 116K on it, and it's cluctch was going strong for the last 60K at least). What advantage would I see in the McCeod? Does clutch tech advance, or has it been the same for a while (or, would keeping one for the next 4-5 years make it obsolete)? Any other insights always welcomed.

Thanks for the advice.
