How to determine???

[85Ram50]

I have had it out before to replace the throwout bearing but I do not remember everything about how I disconnected it. It is starting to look like I have to remove the cross member.
I have the backup light wire disconnected and wrapped up close to the trans, disconnected the e brake and clutch cable. About to tackle the drive shaft. I didn't think of those seals thanks. Any special tools required? I've never done it before. Also it looks like two different sizes of rear crank seal on RA. I wonder what those gaskets are for?

Edit. Got the Drive shaft off loosened the bolts on the trans and trans mount. I shouldn't have to take out the cross member the mount unbolts from it which brings me to a new mount. None of the three on RA look similar to the one I have. I should have taken a picture before I cleaned up. That'll have to wait I need to go get something.
Oh yea the exhaust manifold may be cracked. Yippeee.
