cv joint problem

well i was in need of 2 new cv's on my del sol when i got it and since ive done cv's on a few cars i jumped into it. now im stuck the passenger side cv will not go in at all ive been trying for about 4 hours to get it in. the drivers side was a snap only took like 20 minutes to do the hole thing. Ive heard of certain cars needing there cv's put in in a specific way like passenger then drivers side or vise versa does anyone know if this is a possibility because I cant get it in. any help would be appreciated i need to have my car on the road by tommorow afternoon to get to work

got that preoblem takin care off it ended up getting the cv micrometered and it was just a hair to big so autozone gave me a free set of bosch platinum +4's because they gave me the wrong cv which is fine by me got everything installed and hopefully good to go havent drive it yet.
