I have a few questions. I cant put it back on because the holes for the bolts are rusted and cracked.

1.) I cant seem to find a place online to find one. Anyone now where I can get one and how much does one cost?

2.) Do I need one on it or can I just take it off?

3.) Do you guys think I should also replace the O2 Sensor because of the shroud leaning on it?

Is there a part number visible on the shroud? might have luck googling it.

Personally, on a 14 year old truck, I would simply remove it.

If you feel like attempting to remove a 14 year old O2 sensor, go for it, I would leave it if no codes being thrown.

Yoko, I don't think there is a huge issue there. Washers, or "washers" made from sheet metal and holes drilled can be used to hold that heat shroud on. If any attaching screws/bolts broke off that hold that on, a mechanic should be able to drill those out and repair. I don't think I'd run without it, it's there for a reason; I doubt a replacement part would be costly, it's not really a precision-made part. That part would be dealer-only as new (if still available) or from a parts yard.

As to the oxygen sensor: there's always a chance that removing it might damage the threads in the exhaust manifold, I don't think I'd remove that unless there's a driveability issue.

I went and found the heat shield from Nissan parts store. So I order it, and then I get an email from them saying it Discontinued.

so I might just look at a junkyard or warp it up.

Often the bolts would loosen and fall out, but sometimes they would break. They seem to always break if you are trying to remove them! If they just fell out, I would clean up the threads with some rust penetrant and a 6Mx1.0 thread chaser. Then, I would get some slightly longer 6Mx1.0 bolts and flat washers (as previously suggested) to secure the shield. If you can't, then it'll be okay with removing the heat shield. It'll be fine and won't be the first one. I wouldn't be worried about the sensor.
