z3 fenders

i got some z3 fenders off of ebay and the guy said they were for civic or crx and me being the dumbass that i am didnt realize that the two were alot different and it was either one or the other. Well i got the fenders and put on on and the bottom wasnt long enough and the corners didnt fit right. Anyone know what to do or does any one have civic z3s they would like to trade for crx z3s? :mad:
