70 #s is an underestimate...
That thing feels like 100+ whens it comes down.
And you don't need to remove the whole bracket, just get the forward part that bolts to the bell housing and leave the L bracket part on the X case.
Remove the Vent hose, VSS plug, and fuel line bolt.
I got one of those Metrinch socket sets that fits multiple size bolts and the DP bracket was no biggie. It comes in really handy with these half SAE half metric GM creations.
The upper bell housing bolts are the bitches.
One holds the dipstick tube, thats the bigger of the two bitches.

Get lots of extensions and sit up back by the tail and work in from there.
Make sure you get the TC full seated and its not a bad idea to fill it as much as you can before in stalling it. Some people soak them in fluid the day before so they don't get dry startup. I fubbed and didn't fill mine.
Going back together make sure you have help putting the X case in b/c it needs ot slide on straight and not bind, helps to put something on the gasket to hold it flat during install.Just some stuff I ran into doing mine.
