Flange between the exhaust and manifold for 1970 Pontiac GTO


So the connection between my manifold and exhaust is not tighten enough and making a loud noise so before I tighten it and mess up the flange or gasket in between them where can I get the flange and bolts? Thanks for all the help. I attached the pics.

I would contact Ames Performance Engineering, they have the flanges and the correct bolts. They also have the down pipe (header pipe) if you need to replace that.
