I got the balls out. The replacement balls were smaller that the balls that were in the tower. Both springs were broken. I got replacement springs from a friend, we have no ideal what they came out of. We used a punch to press down on the ball and spring and moved the shift rail forward. I should say I used the large balls. After the T-90 was installed it is stiff to shift. Have not driven it enough to give future information.
Looking forward to the T-18 instructions. I did replace the rear seal to stop an oil leak. There has to be a better way to remove the seal than the way I did it.
Again thanks for the good instruction on the T-90 rebuild. When you get the Shift tower instructions I will complete that.
