sm465 help

[southernrock]

I have a sm465 which I planned on using. I had the transmision tilted forward on garage floor to keep all the gear oil from running out through the countershaft bearing but I shortly noticed gear oil dripping from the input shaft. Is this normal or is there a seal which should be replaced? Also after the transfer case was removed and I could turn the mainshaft more easily, I heard a slight scraping noise. It seems to be there in all gears. The transmission has been sitting for a few years but seems very tight and smooth. Any advice would be great.
