Is there a source for these?

I need a 1" longer stud.

Found them:

Hemi Performance, the Australian company, has them.

They are described as "overlength 7 16 wheel studs".

If you have the length and thread pitch, you can also get from summit...or if you have a local "real" autoparts store with
the orange Dorman bins, a quick search through Dorman's catalog may find a bin with what you need.

That being said, you may need a stud cutter/swedge if you are removing the original studs out of an axle or disc....
Also they may not carry the reverse hand thread Pre-1968 studs and if so you will need studs for the drivers side of the
car for the rear axle and a dozen normal lugnuts...if your car is of that era and so equipped.
