Re: subframe bushing
Two ways:
#1: use a mig to weld a blob on the bottom of the bolt; then use a large pipe wrench (it is self gripping, the harder you turn the harder it grips) to remove it. The heat from the weld will help break out the rust.

#2: same as #1 without a welder, but hit it with a propane torch. Can only be done if there is enough shaft of the bolt left.

Somewhere I have a thread that shows the (low-res) pictures of when this happened to my '93 SE after it's L67 swap.
