Master cylinder differences? (Page 1/1)

Can anyone explain the technical differences between the 84-87 brake master cylinder to the 88?

Two different part numbers are noted.

And looks like the 88 MC was unique to the fiero model year...

Thanks,

Due to fluid volume requirements between the pre-88 calipers and the 88 calipers, the 88 master is different, as is the brake bias valve.
