CA WTB 1969 C10 RWD RH side (driver's) exhaust manifold for 307

[RThree]

I'm looking for an exhaust manifold to replace my driver's side exhaust. I recently purchased a truck that was driven (probably for years) with a closed/malfunctioning manifold heat riser. The exhaust burned a hole through the side of the manifold. So, I need a new one. I've got a 1969 RWD Chevrolet C10 with a 307 all stock.
