they will most likely fit your car, as long as they come from other E36 or E46. There´s tons of rear spoilers for e36, from literally dozens of online retailers. The best one to buy from....that´s your choice based on your taste, budget and possibly location. Shipping charges can be high, since a spoiler won´t fit in one of those flat-rate boxes

. Though one question remains: do you want a different spoiler to be installed using the already existing holes in your trunk lid? I hope you succeed, but I´m under the impression different models, even from the same company, will probably use different mounting points. You can try dtmfiberwerkz or any other ebay store to get an idea.Good luck
