Feynman's perihelion of mercury calculation using field theory

[CarlB]

I'm interested in reading Feynman's calculation for the perihelion advance of mercury that used quantum field theory calculations of graviton interactions. Anyone know where it's published or a good source on the web?

Of course I've googled physics forums and haven't found an answer.

Is it in Feynman Lectures on Gravitation
