It is tight. The shield has to be removed to gain acess to the attaching bolt. Be carefull not to drop the little rod behind the modulator.

No easy way. It is tight as I said. You need small fingers to get in there.

The other way is to remove the cat converter but it is time consuming and on a vehicle that old, you may encounter issues with rusted bolts.
