Yes, it is. If you PM me your email address and I'll get it off to you this weekend.
Be aware though that after recently working on a 67 10536, which I believe to have an original wiring harness, I found some differences in the wire colors to the headlights than the wire colors for the 10502. So there are now two separate diagrams; one for the 10502 and one for the 10536. The accuracy of the 10536 headlight wire colors is still in question until such time I can confirm/deny what they actually are.
