1952-59 Ford 272 Plug wire holders

I did a search before posting this, but could not find what I was looking for. I have a 272 Y-Block. Could someone post a picture showing the proper placement for the spark plug wire holders? My car never had them, and I want to throw a set on. (I've seen them for sale in various cl***ic Ford catalogs.)
Thanks, Mato

 

Here ya go...

 

Thanks. (Not too hard to get to.) Yikes!

 

Not only hard to get to but if your using larger diameter wires they are a real pain in the ***. My engine is out and the 8.5mm wires were a lot of fun to get in the holders.
