HI Elijah, I am sorry to hear of your family's loss. Thank you for the picture it helps a lot. Your little ground strap from the Distribitor body to the point plate, that you marked as D is still in good condition however it is installed wrong on the points end it needs to be mounted on the top side of the points and under the mounting screw head in the rear. While your working on that little ground strap wire take a wire bush and clean up both the connector loops and their mounting points, and the mounting screw heads that can help in improving its grounding. The Number one issue though is that having the ground strap between the point plate and points won't let the points to set down on the point plate properly. There also should be a Gromlet on your new point lead wire that's coming through the Distribitor body to protect it from any rubbing damage that could wear though it's insulation, if you can't find a new one you could take that off your old lead wire and side in onto your nice new one. The Distribitor is the correct 1968 type and looks to be in fairly good condistion so it should work fine. It's probally ok but it might also help some if you clean up the plate plate of any grease, oil, and dirt by wiping it down good with a rag. There is a grease made to lube the point rubbing block of the points which helps them to last much longer too. I am fairly confident that with your new coil and the above minor fixes your engine is going to start and run great again. Best of luck
