1940 trans question.

[1oldtimer]

Put my spare trans together and have a question. Which is more important to have the spacer ring between the syncho sleave and the input shaft or the front bearing seating all the way to the snap ring. I checked to see if the rear bearing is seated and it is, but with the spacer in there the front bearing will stop at maybe a 1/16" until the snap ring rests on the case. Not my picture, it's off google.......but that's the spacer I'm talking about.
