emergency help! lawn guy smashed my window!

I need help guys.....
The lawn guy hit a rock with the weedwacker and it went right through my rear hatch (the small window not the big one).

The part is over $300 but he is going to pay. I was able to remove all the plastic panels on the inside of the hatch to prep for replacing but now I am stuck. (I haven't ordered the part yet)

There appears to be two plastic push pins attached to the little window holding it to the hatch.
Does anyone know if I will need to remove the spoiler and the panel with the Toyota symbol to be able to do this or can those stay in place.

Is this very involved like: making the dealer do it kind of job?

The guy lives across the street so he isn't going to get away

 

granted but if I want to ensure all the clips all replaced correctly and everything gets back to normal either:
attempt to have a dealer do its
or
do it myself

I really would be grateful if I just knew if the emblem panel or the wing had to come off to do this.....
I suspect the wing has to come off (I HOPE not though the dyi guides took like they always result in a wing damaged)

 

this glass is stamped Toyota in the lower right so I am going to make sure this guy is pay for an oem replacement. Plus this isn't just glass, there are two plugs for the heater wire.

Update:
The spoiler does need to be removed. I read all those posts about the "devil clips"- these are wrong. Just unbolt the 5 nuts from under and rock the wing off. There are two push pins that hold the wing down on the ends that is all.

So I got the spoiler off and now all that is left is the window. I removed most of it but there is a thick rubber gasket (2 way stick) that holds the glass to the car. I do not know how to remove this. It is reaaaally stuck and even with pliers I can barely get it to budge. See the pictures below.

Any suggestions? Hairdryer and razor? I do not know what to do but I think a replacement gasket is part of the replacement window assembly.

On a side note, a lot of glass fell into the pockets of the hatch. When the hatch is opened and closed you hear all the rattling in it. This is the kind of thing I will clear out and that a repair shop might do a crappy job on. This is the reason why I like DIY work.

 

normally I would agree accident and all but I live with someone that works with the guy. This is not the first time this has happened. The last time, people just pretended they did not do it. Because he lives across the street in this case, he did not even try that.

So first time? accident. Track record and still trying..... no.

The window and rear plastic panel has been ordered at the guys expense. It came to $489.61 but the guy gave me a check for $500.
His wife said I should just make a claim on my insurance. I do have glass with a $500 deductible. This is not the solution. The guy has to learn to not edge with the weedwacker. Had it been my solar panel that would be $1600 for the panel alone. He is lucky I am saving him a few hundred by doing the labor myself.

Granted, one of the plastic panels died by my hand and I charged him for it but if I had a body shop or Toyota do it then it would have been a lot more.

The amount of glass in the hatch is insane. I spent a few hours digging, probing and getting most of it out. I hate rattling and one piece of glass can make a lot of sound.

The parts will be here Monday. I was already cutting off the rubber seal when the video was posted so I shaved a little close. In some cases undercoat was exposed but that will all get sealed up again anyway so I don't care.

Some pics attached below

 

For reference,
the glass is part number 64821-47030 $309.31
the plastic panel on the hatch with the handles to close (in black) is 67750-47071-c0 $141.42

 

job done, all back to normal.

wow I cannot believe how many people are anti do it yourself-
This was a "free" chance to learn how to do something and hopefully this thread can help someone in the future because I seem to be the first to try this here.

The only expense not initially accounted for was the urethane. Like the video suggested, the old stuff does need to be cut off and a new bead applied. a tube of quality stuff is around $25

But now I have the confidence that the bead was applied correctly and every spec of glass was removed before putting everything back together. This was also an opportunity to refresh all the pads under the spoiler.
