Looking to put new grounding straps on my Hemi, since all that's left of the old ones are about 1/2" nubs. Hoping fixes a weird computer issue.

The valve cover studs are very old and very rusty and I am very worried will break. Ideally since the tops are threaded I'd like to put the grounding wire there and just add a nut but not sure if thread good enough to use, and if too rusty to ground properly.

I researched and I think I need MOPAR 6507366AA for the stud/grommet but wow! After shipping it's about $40-50CAD per stud. I've seen a few aftermarket, ARP makes one for example that looks like bolts with undersized washers. Off chance I need to replace a bolt on either side, does anyone know what I need? I'm not sure if in '03 it would have been imperial or metric, or length needed etc.

Does anyone know what the threaded tops are on the stock bolts?

I mostly do wood work, so, I have nails and glue... not a lot of extra bolts/nuts so would need to grab some at the hardware store but I don't have anything to measure what's there with (thread wise).

 

Go to a hardware store that sells nuts/bolts by the pound. Then just take a nut with you and you can determine diameter and pitch thread.

 

I don't want to remove the bolt unless I have to in case it messes up the seal on the valve cover.

 

If it's a problem, ground the engine elsewhere. Doesn't have to be on the valve cover studs.
