2G Are 1g and 2g clutch master cylinders the same?

[Kai Hefner]

As the title states. I need a new clutch master cylinder, are they the same from 90-99?

Rockauto shows completely different part numbers for 1990 compared to 1998.

No way, the 2g has a port in it that can be covered by the piston that has been said to be a factor for crankwalk in the 2g, the 1g doesnt have that setup, so for that reason alone they are different and I'm going to say that there are many differences between them, that just being one of them.
