Building an Engine, Part 3

Now that we have the crankshaft and piston assembly, we need something to hold them together.
---Today's Brick---
Name: Technic Cylinder Casing
Size: 2 wide x 3 deep x 3 high
Color(s): several
The pistons go inside these pieces, through the hole in the center of the piece. The cylinder casings are then arranged in rows, sometimes opposite each other, sometimes in a "V" shape, depending on the engine configuration. But, how do we faster these pieces together? The studs are in the wrong place! Good question; the answer is coming tomorrow.
