65 Barracuda daily driver

So it looks like my timing chain is bad. Below is the only photo I took when I had the engine "apart". Back I didn't notice significant slack, so I just left it like it was. Anyways, there was some fluctuation on the timing light and when adjusting the idle mixture with a vacuum gauge. So today I popped off the distributor cap and turned the crank back and forth and watched the rotor. There's 10+ degrees of slack before the rotor moves. So I guess it's time for a new one.
One thing I noticed in the photo is that that little oil drip tab appears to be missing - even though hard to tell from this angle. Some folks here on FABO seem to think that they're not necessary, but it might have actually extended the life of this chain. Too bad I didn't replace the timing chain when I had the oil pan off replacing the oil pump. I've been looking at the Cloyes C3028 double roller timing set - any thoughts on that one?

I also still had a pretty bad ATF leak which seemed to come from the neutral safety switch. I had already replaced that weird washer gasket. I almost feel like an O-ring would work better.

I took the switch out and the were some remnants of the the old washer. By the way that new washer was pretty much destroyed when it came out.

After cleaning the hole as good as possible (with the exhaust in place it's not easy to reach) I got rid of it.

The new old switch was almost 70 bucks, but totally worth it if it actually stopped the leak.
