How to remove shower valve?

My shower has developed a leak and it's been getting worse over the last few months. I've done quite a few plumbing jobs but I can't for the life of me figure out how to remove this stem! This is the original valves from when I bought the house 12 years ago and the first time I've had any troubles.

I've tried pulling and twisting with my vice grips on the plastic parts of this stem but it won't budge. How do I remove this stem so I can replace it?

Where the plastic stem enters the metal housing you may need to try and insert a flat tip screw driver to try and pry while with pliers on the plastic stem wiggle it side to side pulling out.

Could you show us the rest of the valve, the parts you removed, but I am thinking that, that insert just pulls out of the valve body.

When its all said and done there is usually more said than done

I wonder if I need a special tool or if I should just grab down on this part with my vice grips and pull like mad to rip it out of the copper pipe and hope I can find a replacement part before I need to turn the water supply back on.

Here are the rest of the parts, one together (on the left), the other exploded

and this other photo shows how the plastic "alignment bit" fits inside the copper threads (my hand included to make my camera phone focus properly). The parts available at Lowe's all had two "alignment bits" on each side of the part but mine only has one.

replace the valve,quit "screwing around"! access behind the shower and take off the wallboard so you can get at it. you'll be glad you did! that's what I had to do.

Looks like a cheap valve, most would have used brass.
It also looks like it would unscrew not just pop out. See the threads under those plastic tabs?
