What's the diff. between slaves?

[Pimpin Dsmstyle]

I need to know what the differences are between 1g slaves.

The car we are trying to get one to work in is a 90 FWD turbo laser. The tranny is supposed to be out of a 91 FWD turbo talon. I am not sure how to look up and purchase the correct part. I would prefer not do a guess and check since once a part is used, it's not usually returnable.


Thanks
