I got some ARP .580" knurl studs. They are too big even though the package says "late model disc, early drum brakes".

I called Summit today and got a moron operator. He told me they don't make studs for 10 bolt 8.5 factory axles.

I ordered the .486" knurl studs from a different operator at Summit. Will these work???

It may use metric studs if the standard don't work.

It is a '73 Camaro. There isn't anything metric on it.

Some of those catalogs are wrong. I don't know about a '73 Camaro, but my '72 Nova has front discs, and the knurl on the front studs is bigger than the knurl on the back ones. The NAPA catalog had them listed wrong, and I ended up walking all over Monroe LA one day looking for a few big ones.

Sorry, lluciano77 threw me. I assumed it was a 1977 since you didn't specify otherwise.

I got the .486" studs today. They look like they will work.

I still have the .580" studs. I think they will work in my front wheels. Is there any benefit to studding the front wheels?

[bracketeer]

You only have to stud the front wheels if you are using hollow aluminum wheels such as Centerline, Weld, Bogart, etc.

I have Centerline Convo Pros

The reason for lengthening the wheel studs is to pass tech at the track. Wheel studs must be threaded into hex portion of lug nut a distance at least equal to the diameter of the stud. Most ARP studs are long enough that the stud will protrude all the way through.
