Question

[2003Cavi]

will a stock clutch from a 1990 z24 3.1 fit in a 92 sunbird 3.1 ???

[Superdave]

yes, they are the same.

[Barry]

Yup. 93 and 94 got the internal slaves, and a diffrent throwout bearing. The friction plates are the same regardless, but its possible that the pressure palte is a little different.
But that dosent affect you, your good to go.
