Diesel Bombers - another timing ? help

so im finally getting around to doing my timing, got the truck all tore apart in the garage right now and i cant figure it out for the life of me, does anyone having any simple directions?? all the ones i can find are so techincal its confusing

heres what i have, i found tdc of cylinder 1, how do i set the dial gauge up form here? if i put the gauge in the holder and set it between 7-9 and then rotate the harmonic balancer counterclockwise and i run out of shaft to drop to zero on the cam, i tried pushing the gauge as far in the holder as i could and i still dont have enough

also my gauge was missing the end piece that screws on to the feeler shaft, i called a friend who has one and he said it was a 1-1/2 long piece, so i found one that long but im wondering if thats right, can anyone measure theirs?

send me an email for a phone number as it will problay be easier to go over on the phone

maybe i made my post a little too confusing, its hard to type it out in a way so its easy to read.

i tinkered with it some more just now and think i have it figured out, i found an extention for the dial gauge so i can now read the full movement of the cam, i set the gauge up at a half way point, bottomed the cam out and zeroed the gauge, then turned the harmonic balancer clockwise back to tcd, did my math and came up with a lift of 6.2mm which is 15*, i want to go to 16.5* so im going to keep turning it another .3mm on the guage. then pull the cam gear on the pump, clean the shit out of it and rotate counterclockwise back to tdc???

im pretty sure thats right, my gauge is a bit diff from the one directions on genos garage. the small gauge reads 0-28 and goes in twos and the large one goes .00-2.0 and goes in .1mm
