Mike's got an excellent point, and I have no idea how your AX15 tranny compares to the GM for the transmission front bearing retainer/guide tube. I think the guy in the video pointed out how critical it is for the throwout bearing ID to match to the guide tube OD, and like Mike says, for the guide tube portion to be long enough.
