gt vs st Spoiler question Options

[captb]

hi all. ive had my celica for about three years now and always enjoyed it, but only recently found this forum. anyways, i was hoping for a little help. when i got my car there were doo doo stains everywhere, paint fading and chipping, etc. but i did my best at cleaning it up with wax and rubbing compound and now it is my baby. anyways, my rear spoiler (94 stock gt) is really faded and chipped now but i saw on craigslist a guy selling his 95 celica(blown gasket) same color as mine. he wanted to sell the whole car but i asked if he would sell or trade the spoiler. he is offering it to me for $85. here is the link. it doesnt look stock.

1) is this a good deal?
2) does anyone know if the gt has 3 mounting locations vs the 2 mounts shown on the ad. ( there are 3 legs, but for all i know the middle one might just be double sided tape?
3) if there is 3, how would/can i plug the middle holes?
4) how much would stock, bumpers (front) cost, on average if he were willing to let them go?

thanks
