They are behind the flamblaster, and just in front of the haglemorph.
[Sorry, I couldn't resist.] The TDC (top dead center) timing mark for the #1 cylinder is on the harmonic balancer (one axial line somewhere on the O.D.) and the "scale" for it is attached to the block just above the balancer at about the 2 o'clock position [as you are looking at it from the front].

Mine was missing too, got one at AutoZone, about $5, chrome too!
One problem when installing - the lower (iirc) bolt won't come out all the way because it hits the balancer. I cut the lower bolt hole on the timing tab to make a slot and slid it under the bolt head. The other bolt comes out fine.
