2" exhaust collector flanges?

I'm getting ready to drop the engine into my 53 F250 and want to get the headers ceramic coated before I install them. They are patriot long tubes for a ford 215/223 I6. The headers have 2" collectors.

Maybe I'm not looking hard enough...

I can't seem to find 2" collector flanges anywhere online. I would really like to run true dual exhaust...

Any ideas?

 

what type of flange? two bolt? three bolt? bell type? let me know

 

I was thinking 3 bolt, but I'm open to suggestions...Whatever will work best, really.

 

Patriot sells them in 2 bolt part #H7257 and three bolt part # H7528. You can get them through Summit or Jeg's.
