Timing mark locations on small block covers?

You choices are:

1) The '69 one year only cover used.
2) A used '68 and earlier cover with the timing bracket (both used).
3) Or a used or new '70 and up cover with a used '68 and earlier timing bracket.

I put a wanted ad on this site for the timing bracket and picked up a nice one for cheap.

I tried running a '70 and up timing cover and balancer but I could not see the timing marks because of the lower hose.
