need help asap.

i was replacing my front axles today, the driver side went in fine but when it comes to the passenger side, thats when the problems start. the old axles that were in the car on the pass. side the splines look like an upside down v, i bought new axles and their splines have a more squared look to them. and they wont go into the trans. the car is my daily so. i had to put the old axle back in with a torn cv boot and missing bearings, so i need to get this fixed asap
