Default 5.3 Silverado header/collector help needed

I purchased a 2000 Silverado as a donor vehicle for a Grand Wagoneer I'm building. It is a bit of a basket case. On the y-pipe, the two ends that connect to the header are different types (top pics). One uses a gasket and the other is a ball/socket type (wrong type for connecting to the stock headers). I have no idea that the previous owner was up to with this truck.

ANYWAY...I need help locating the correct collector piece so I can cut off the ball/socket end and weld on the correct piece to mate with the stock headers. This appears to be the most straightforward solution but I may be wrong. I have searched and can't find what I need, so I would be grateful for some guidance! Thanks and I apologize for my first post asking for help.

Go to the junk yard and find the pieces you need - carve them off with a battery powered reciprocating saw. After that, any competent muffler shop can make any adaptation required to stitch it all together. They charged me three dollars each to stretch / widen and slit my pipes after my headers.

U have all the correct parts. The passenger side takes a doghnut gaskets tht popps inplace in the manifold. Its missing in the pics!

The driver side takes a flat round copper gasket. The parts store will have the correct gaskets to bolt everything up. All the silverado trucks are like yours.
