Spark Plug Wire Holders

[fredeuce]

I plan to use the original spark plug wire holders on the 8BA I am building.

The engine I salvaged them from had all of the Left hand side (5-8) wires routed through both holders and all of the Right hand side loose.

Does anyone have any pictures of the original layout ?

Look through this thread and you will find and 8BA with a spark plug wire holders similar to yours. Even though the holders are a different style at their top, I think the routing is still the same.

There are directions and a "photo" on page 57 of the 49-51 shop manual.

Good luck.

Thanks for the replies. Unfortunately I don't have a factory Manual.

Those pictures on that link 19Fordy do give a good indication of how they routed the wires. That basically reflects what I observed on the old engine I salvaged these from. These holders when removed were bent at odd angles as in the pictures although not so easy to discern. A side on shot would illustrate this better .

I wonder if they have become bent over time?

Those pictures would suggest that they should be straight up and down.

They get bent when various folks used a 9/16 socket on the bolt head.

While doing research on the 49-51 Mercury at the Benson Ford Research center a while back, I came across this drawing of the 0BA-12290 Ign. Cable and bracket assembly. I hope that this helps.

Wow, Don, Thanks for posting that drawing.

Don, thanks for that illustration. Great find. Well done.

After some trial and error and some straightening of these brackets this is the arrangement I have come up with. Seems to achieve what is set out in the drawing.
