Changing catalytic converts my self

Anyone already did this and can give me some advice on how to do it? I'm pretty good at working on my truck. (Done a lot harder than this) but on the two front converts it almost looks impossible to undo the bolts on the engine side because the heat shield is in the way. But at the same time it looks crazy hard to try and get that heat shield off. It's hard enough to even see the bolts on the thing. Any advice on how yall did it would help! Thanks (2005 frontier 4.0)

If you have a sizable compressor get a cut off wheel tool with extension.

front flange of cat has 3 bolts. I think 2 are in same direction and can be cut off as new cat will have these 2 bolts at flange. Once they are cut off it becomes easy.
Just look at what your replacing and make sure to cut the right bolts off.

Also you will need about 2 1/2 ft of extension and some swivels to use with a socket. Once you have the extensions in hand you will need to be creative running them to the bolts.
