So coil has spark and the distributor does not. I just post a pic by pic break down of the 83 280zx n/a distributor. I posted it on Zcar (they suck) my name there is series500 and my post is close to the top of the 77-83 280zx thread there and title says "280zx timing issues", I going to talk about how I fix my problem today so it should be right up there, if they didn't take it down because they hate me lol.

Hope this helps
