How do I remove the back seats from my 99 SI (in a way that I don't damage anything so I can put them back in)?

 

crab a clip puller and pull off all the clips on the capret the seat. take off the blots on the seats.
next pull the samller seat out, now theres a bolt holding a bracket on take it as well as the bracket. now pull the bigger part out,

next for the lower part there is 1 bolt holding in to the car. take that off and then push the seat towards the trunk and lift up.

reintall is install reversed.
