Here are some pics of the new CNC'd clutch master reservoir from Ring Brothers. It's made to be a direct replacement to the standard GM plastic unit. It's a two piece design, the reservoir can be slid up and down inside the mounting bracket. It uses the GM lid seal/diaphragm, so the fitment and function is same as stock. It will come with a barb fitting for use with the stock rubber line, but the bottom of the reservoir is tapped 1/8NPT so AN adapter and line can be used instead if you wanted to go that route. The finish is annodized titanium and looks trick.
