I am attempting the plug wire routing method for my 2000 5.2, however the OEM mounting brackets are extremely hard to find.
OEM PN - Mopar 56028186
Are there any other alternatives for mounting hardware to keep the wires off the block/manifold/valve covers?

Surely there has to be some thing aftermarket! I have searched eBay and everywhere else!

 

Moroso has bunch of different variations: https://www.moroso.com/moroso-shop-b...ms-separators/
And if you google 'spark plug wire organizers/separators', you'll get more options.

If you have a good photo of the spark plug wire retainer/separator you need, you can search for it via Google by that photo.

 

EBay has them, copy 56028186 Mopar in the search winow.

 

While eBay does have several options for them, the cost is pretty high. Might want to check pick & pay salvage yards to find some used for a low, low or even free price.

 

I like these...

This is what I was looking for. Excellent. Thank you

 

I researched/looked for wire holders and found these. Never bought them but saved the link. Let me know how well they work out.
