theres a special windsheild knife you can buy for around 16-20 bucks,all it is is a bent blade with a thick handle,as for the adhesive you use to put the new one on,you can find at any bodyshop supply store,as for the pins,those are guide pins which you can cut off,not a big deal,just make sure you use a razor blade to cutoff the old extra urethane adhesive not only on the quarter panels but also the backside of the glass

you'll need a caulking gun for the adhesive,and just make sure you put enough of there so you dont get water leaks,put a tall bead on there and the quarter glass will spread it out more once its on there
