I=E2=80=99m not sure why Ford made the ID # of these distributors Z5TF-C =
unless it was to make sure they did not go to the Ford production line.

=20

The Z5TF-C has nearly the same advance curve as C4OF-A.

Z5TF-C - Ford equivalent is C5JT-C

C5AF-M is the MK II distributor

=20

The vacuum canister for all these distributors is similar but not the =
exact same.

=20

The early canister B9AF-12379-A has threaded boss.

The later canister C5AZ-12370-A - later style with no threads =E2=80=93 =
threaded boss is on distributor housing.

=20

You need the later style canister.  Use C5AF-M for the ID#.

=20

I believe most or all the vacuum canisters available today are the later =
style and many of them have an internal screw to change the vacuum =
advance.   All of these use a vacuum hose not the original steel =
hardline.

=20

For concours, there are some shops that rebuild the original vacuum =
canister.

Ron directed me to the right part number location, and the number there =
is Z5TF-12127 C.This number also doesn't appear at any of the usual =
parts sources.=20

An article on the CAT forum confirms that this is the correct Tiger =
distributor, and there is mention of it on a few other sites.

=20

But is Z5TF equivalent to any other Cxxx distributor numbers, at least =
for vacuum advance modules?
