need help asap

[87sierra]

I need some help removing the gauge cluster. I'm not sure which bolts are holding it in if anybody could post a picture or explain how this is done I would appreciate it.

Also my service engine light came on earlier and I ran the diagnostics and got a code 24. When I looked that up it said vss error or something like that. The speedo isn't working (actually only my battery and gas gauge work) so I was wondering if that could be the problem and if so how do I fix this...I was going to check the vss behind the cluster but...lol
