I find Rock Auto's website (www.rockauto.com) to be very helpful for things like this. Look up your truck and drill down to the part you need. Select any of the options for the part (master cylinder in this case) and click on the blue part number shown in the description just after the manufacturer's name to get a cross reference list. According to this, the Buick master is not a match.

I believe the master cylinders are the same for manual and power brakes. Just about certain.
