Where are the freeze plugs on a 98 Tahoe located?

There is 8 of them in that engine. There is 2 in the back of the engine between the engine block and transmission. There's 2 on each side of the engine just below the heads, 2 of them are hidden behind the motor mounts and 1 is behind the starter and you can see the other one on the drivers side towards the rear. Now there is 2 more on the front of the engine 1 on each side of the timing cover. You can't see them until you remove all the stuff that's bolted to the front of the engine. That makes 8
