93 Celica Drive Shaft

My 1993 Celica, 1.6, 5-speed manual left drive shaft failed and I am trying to replace it myself. I have the new part in hand, but for some reason, the inner splined shaft does not want to go all the way into the transaxle. I have tapped the rotor end of the shaft with a mallet and tried to force it in, but everything Ive tried wont work.

Any ideas? ANY help would be appreciated since my car is down for the count until I can get this drive shaft back in.

Back it out and make sure theres no obstructions. If the is a ring at the end of the shaft make sure it is as centered as much as possible. Make sure it goes in straight. Good luck...

Turns out I had the wrong part. '92 and '93 aren't the same. The splined shaft is a different size.
