Not directly, since they are Opel-specific, but a common piston substitute is the Chevy 265 0.030 over, machined slightly for deck height, and the cylinders over-bored to fit (gives a 2.0 litre displacement)

Chevette's are totally different. It is probable that the Opel transmission input splines would fit the early Vega friction disc, but I don't believe that the pressure plate has the same bolt pattern as the Opel. And if you're going to re-drill for the Vega pressure plate, then you would use the Chevy S-10 2.8 clutch
