the timing pointer is a line on the balancer, and there are marks cast into the timing cover.

The trans is ither a 3.03 3spd or a 2.02 3spd.. 1st gear is not synchromeshed on a 2.02 but is on a 3.03.. so if you grind gears going into 1st gear moving, it is most likely a 2.02... should be a 3.03 but with with Ford.. you might have a 2.02

If it is the clutch, all preassure plates are rebuilt units, and from what I'v heard you should inspect them b4 installing as there worn out.
