Timing marks?

[dk05]

I was wondering if anyone knows what the timing marks are on the 1985 305 TPI? I tried to do a rather crude drawing of what I can see from the drivers side of the car. Hopefully you can make sense of it. I have the Chiltons but it doesn't say anything about the marks. Oh yeah, but under the hood it says "6 degrees BTDC" but which mark is top dead center and is there one to line up to be exactly 6 degrees before top dead center. Or to put it a better way, what mark is for factory timing? Thanks

Scrub the timing tab with steel wool and use a bright light to look at it, the degrees are on the tab.
