Offered here is a limited, Assembly Line "correct" Reproduction of the 1967-1969 (and possibly later) Distributor Primary (Distributor to Coil) Wire, Part Number C7VY-12216-A.
According to the "Bible" of small blocks, Bob Mannel's "Mustang & Ford Small Block V8 1962-1969", this would be the "Factory correct" wire for all "non-High Performance" 289 and 302 Mustangs from 1967-1969.
Note that the 90° push-on connector for the Coil is Yellow (Factory correct). Unfortunately, the majority of Ford Service Parts for this wire were made with Black (although I have seen some Green) 90° connectors. In addition, the "Repo's" that are available must have used the Service Part as a "guide", as they are also Black. I have never seen a Ford Service Part or other Reproduction of this wire with the connector in the Factory Correct Yellow.
Interestingly, the 1960-68 Ford Master Parts Catalog also shows this C7VY-12216-A wire as correct for 1967 and 1968, 390's, as well as for 1967, 427's and 1968, 428's. Not knowing such details on these engines, I will leave that determination to the "Big-Blockers". To help, I have also attached a picture showing all of the dimensions of this wire.
If any of the "big block people" reading this could confirm or deny that this wire is "Factory Correct" for the "big blocks", it would be appreciated.
Rather than just take what is printed in the MPC as "Gospel", I have left the "big block" suitability of this wire to "those in the know". I say this because, while the MPC shows the C7VY-12216-A wire as correct for 1968, 289 and 302's, it shows that 1967, 289's use the C1VF-12216-A wire. The C1VF wire has a ring(eyelet) connector for connection to the Coil, and requires a nut and lock washer to attach it to the Coil. Based on Mannel's book and many pictures of un-restored 1967, 289's, we know that the ring connector is not correct ; the correct connector for 1967, 289's is the 90°, yellow push-on connector.
I only have 6 of these currently, so "first come, first served". Of course, if the demand warrants, I can get more made, but that might take a few weeks.
Price is $36 each, including shipping to lower 48. Shipping beyond the Lower 48 may be able to be arranged at additional cost.
