Ok. I've run into a problem. I had the entire final drive apart, including the front bevel drive gearcase. I got it all put back together, and realized I had forgotten to put the clutch rod back in. Yeah, stupid I know. So I removed the bevel gear case, and managed to pull the driveshaft out of the rear gearcase. I figure there is a good chance I can get it reengaged at the rear, my question is, since it came loose, is there any possibility the spring could have fallen out on the rear end of the driveshaft, meaning I have to tear everything apart again?
