Where to get replacement pre-cat exhaust flange (3RZ)

Hey folks, I bought the LCE Street Header for my 3RZ and not until I was about to try and install it I realized that the PO had the catalytic converter replaced (due to theft) and the pre-cat flange is no longer there. Does anyone know where I can get the OE style flange that will mate up to the new header?

Here is a picture of the flange in question:

 

I just purchased this.. seemed to match the dimensions but we'll see.

For documentation's sake, I'd like to confirm that this flange worked out perfectly. Shipping was crazy fast.. ordered on Saturday and received it this morning!

 

Looks good.

A muffler shop would probably hand you one(or two, or three) out of there scrap bin,,,for next time.

 

The guy actually cut it, swaged it, and put it in my hand in 1 minute flat, for free! I left a bill on the counter for some beer
