[Tigers] Clutch fork.... Still....

    Ford could change the a part number several ways.

The year code could change - C3 = 1963, C5 = 1965, C8 = 1968.
Generally a year code change means the part was updated somehow but I'm
can't say for sure.
Many Ford parts had the year code change for the 6 bolt engine change over.


The 3rd digit is the division where the part was first designed - A = full
size Ford, O = Fairlane, T = Truck, Z = Mustang
This digit can easily change.

The body of the number for any part will not change - 7515 = clutch fork all
across Ford.

The last letter in the number is the revision level - A,B,C to Z.

The correct Ford Parts Manual will show if an older part has been updated to
a newer part number.
This is similar to the Rootes Parts List that show superseded part numbers.

I believe David Franchi has that kind of Manual and it is not showing a
direct replacement part for the Tiger Clutch fork.

Ron,
I don't have a manual handy, but maybe you can explain the reason behind a
single change in digits of a Ford part number.  I know, for example, that
one digit represents the application of the part.  As I understand it, if a
part is changed the number will change, but the new part might still work on
the old application.

In the list that Dave presented, one or two of the part #'s changed by one
digit. Could we have something similar with the Tiger clutch fork.  In other
words, is a there a number that is close that will work on the Tiger.
