Exhaust seal ring

I have a Ford 755 that was loaned to me on a permanent lifetime loan In trying to get it running and ready to take to the house we are repairing I needed to repair an exhaust leak at the turbo
the connecting tube lists for over $200.00 and is not currently available anyway.
I wasn't going to spend that much for one at any rate. SO what I did was take a piece of 22 ga sheet metal and made shim to take up the space between the tube and the mounting plate
