3.4 TRD headers 2 Bolt Flange part number

Anyone have a part number for TRD 2 bolt flange?
I have talked to 10 different Toyota dealers, called TRD, searched all of the googles and cant find the proper information. Only thing I haven't done is call Toyota headquarters in Japan.

Basically I've already ordered 2 different flanges. Both where 2.5'' (i.d) but neither line up with the TRD header flange. The ones Ive got from Amazon both had a bolt spacing of 3.5-3.75'' as the TRD needs a 4.25''. I did look in to a 3'' i.d flange and that has the correct bolt spacing but the wrong size for exhaust pipe.

Hopefully someone has a part number or a link to a correct flange.

Btw this is the flange that is welded on to the stock catalytic converter in order to mate up to the TRD headers.

 

Here are a few more pictures with the sizes:

 

A little late, but if someone sees this I used this flange from LC Engineering part # 1041001. I found some TRD headers on ebay and used this flang buy cutting and welding to OEM CAT.
