G8/CTS-V Manifold Flanges

Anyone know where I can get a g8/gen 5 passenger side manifold flange. The bolt spacing is 3.75 " on that one.

I also need a passenger side cts-v flange. The spacing on that is 4.45".

Any ideas guys?

I found these but they will only work on the g8 manifold

A little porting/die grinding and those will work. I used the ones listed for c6 ls3 manifolds and had to tweak them a little. I did weld the flange to the manifold though so you are on your own for sealing if you want to use gaskets. I think the factory gasket for the manifold would work on those flanges though.

i used flipped g8 manifolds on my turbo fairmont, i cutthem after the flange and flex pipe though and welded the vband on the bottom of them.
