First post: neutral rattle

Ah. I was calling that the input bearing, but I got you. That makes me feel better in a way, since I had been considering changing the bushing that is in the end of the crankshaft, that I had been calling the pilot bearing, but slacked off. Now the problem would be finding the proper bearing for a Doug Nash 5-speed which is no longer in production, if I'm not mistaken. I'm going to top off the trans oil and say a 'Hail Mary'. If that doesn't work, I'll worry about it next season. Thanks for the help.
Also, how hard is it to replace that bearing. I seems like I should be able to remove the input bearing retainer, and slide the needle bearing out. Or is that just wishful thinking on my part?
