[Tigers] Distributor Vacuum advance Round 2

[Ron Fraser]

I’m 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.

 

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

 

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

 

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

The later canister C5AZ-12370-A - later style with no threads – threaded boss is on distributor housing.

 

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

 

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.

 

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. 

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.

 

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