Mallory HEI distributor Help.

[csfdfirefighter]

Hey guys, so I have been putting off figuring out why my 69 C10 hasn't been starting.. Traced it pack to the distributor. Unscrewed the four screws on top and found that the yellow wire was severed. I was barely manipulating the top to see how i might replace it and the red one broke as well. I am semi mechanical but mostly on new cars.

I have been learning from the great help you guys have been giving me. Can someone tell me or show me where I can find directions on how to replace this?

thanks so much.
