Bellhousing/rear main removal

Tommorow the clutch comes out and the new one goes in, can i get at the top bolts for the bellhousing from the bottom once the tranny is out? They look like it would suck to try and get them from the top side, any tips tricks on getting it out? I am also replacing the rear main while in there, anything weird about getting it in and out that i should know? Thanks for the help Dan

Thanks Dave i will sleep better now, it did not look fun if i had to try and reach them from the top side, my bro's 66 has tons of room everywhere, which mine was like that. thanks again dan
