[fiero128]

three of the bolts that hold the cradle up are snapped off
After all this time ,
I am trying to remove the bolts and cant right now
They are hardened and the drills i have cant even make a hold in them.

It's a drastic solution, but for the horizontal bolts in the front, cut the heads off with a cut-off wheel and drive them out with a hammer and punch or piece of rebar.
For the rear ones, cut the heads off and work on them after you remove the cradle.
