LT1 o2 sensor needed

[IROCZBeast]

So after finishing my header install and having an electrical problem where I kept blowing fuse 10 aka engine sensor fuse cause of what I thought was a short somewhere, it in turn killed my maf and my reverse was always lockout.

I finally figured out that this was all being caused because one of my o2 sensors had gone bad.

Before I spend the money on a new one I figured I'd give it a shot trying to just put another o2 sensor in from another LT1.

I need a before cat o2 sensor aka the the one with the the four prongs straight across not two over two.

Thanks.
