Vauxhall use the bosch 60-2 system (60 teeth minus two)
Fords use 36-1 (36 teeth minus 1)
Those are basically the most popular ones. The 60-2 seems to be far more popular than the one ford use.
You're old 1.6 8V could have one if it was one of the very late 8v's The 1.4 8v MPi engine had one. On those engines they are located at the crank shaft pulley. They have the teeth on the back of the pulley, and the crank angle sensor sits on a bracket. On the XE the wheel is inside the block, and the crank angle sensor sits in the block.
I would say yes, they are both bosch parts and only measure the crank rotation which is the same on both engines which is going to be the same for any 4 stroke. It's down on the front of the engine near where the power steering pump normally fits I beleive, but not sure.
