I wonder what else used the 606 casting? Smaller V8 cars, since it only fits the 153-tooth flywheel and 10.5" clutch.I had a Monza bell on the 350 in my Chevette since both used a cable setup. The fork came out at the perfect angle for the floor too.
I'm pretty ashamed of myself for overlooking this... I just googled the casting number and bought the first one that came up on ebay
