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.

Excellent work!
Maybe Gene still has his  C3AZ clutch fork handy and can measure from the
fork tip to the center of  the clutch rod dimple.

I went through all my parts and unfortunately I  don't have a MK1 Tiger
clutch arm/fork Ford number C3AZ-7515-A. I do have a  couple of later arms
which may help people locate a suitable length arm. I  also checked on what
clutch arms are shown in the Ford Factory Master Parts  books. Here is what
the Ford parts book shows: C3AZ-7515-A 10" (same as  Rootes MK1 Tiger),
C5OZ-7515-A (MKII Tiger 289) this number is NOT in the  Ford Parts book
(mis-print by Rootes?),  for the 1965 289 (6  bolt
bellhousing) Ford shows C5OZ-7515-B  9 1/4"  up to date  2/15/68, then for
2/15/68 up they show C8OZ-7515-B 10 1/2". I have examples  of the 
C5OZ-7515-B
and C8OZ-7515-B (pictures below) They are almost  identical except for how
they mount on the pivot inside the bellhousing and  the tip. The (C5) 1965 
(6
bolt) mounts inside the bellhousing with the same  round wire clip as the 
MK1
Tiger, the (C8) 1968 mounts with a flat spring  clip. Now the actual
measurements of these clutch fork arms don't match  what Ford has listed in
their parts book, I don't know how Ford measured  them, overall length, from
the fork end to the pivot, or?  The C5OZ-B  is shown as 9 1/4", the only
actual measurement which matches is from the  tip of the fork to the center
of the round clutch rod dimple, but the C8OZ  is shown as 10 1/2" and this
arm is almost the same as the C5OZ, the whole  arm on the C8OZ is 10 3/4".
----------------
Here is what Ford shows,  and my measured actual lengths:
-
C3AZ-7515-A (MK1 Tiger) - Ford 10",  actual overall, or tip of the fork to
the center of the round clutch rod  dimple?
-
C5OZ-7515-A (MKII) not in Ford book, Tiger owners report 9  1/4" (measured
where?).
-
C5OZ-7515-B - Ford 9 1/4", actual 9 1/4"  tip of the fork to the center of
the round clutch rod dimple, and 10 1/2"  overall.
-
C8OZ-7515-B - Ford 10 1/2", actual 9 1/4" tip of the fork to  the center of
the round clutch rod dimple, and 10 3/4" overall.

I  think the measurement should be from the tip of the fork to the center  
of
the round clutch rod dimple, but the Ford C5OZ-7515-B and  C8OZ-7515-B
measurements don't match (Ford  mistake?).
----------------
So, is the (MKI) C3AZ-7515-A Ford 10"  actually 9 1/4" or 10 1/2" or ?,  and
close enough to the 6 bolt  non-Tiger C5OZ-7515-B  9 1/4". Since the Ford
parts book measurements  don't match all actual measurements, I think the
Ford 6 bolt 9 1/4" arm  C5OZ-7515-B should also work on the MKI. Also is the
Tiger Parts book 6  bolt MKII arm C5OZ-7515-A a misprint, and is it actually
a C5OZ-7515-B? or  is it something special? Boy is this confusing :)
---------
For John all  the arm measurements. L= 10 1/2, IN= 1 11/16, CC= 2 3/8, SE= 4
1/16, SD= 5  1/8, SP=?
