8 3/4 axle vent bolt

Does the 8 3/4 use a special bolt or are they the same as an 8 1/4 and 7 1/4?

I have a 7 1/4 and it is different set up.

You might want to give the p/n to your local Chrysler dealership, I bought these direct from them as little as 3 years ago. They are probably still available. People advertise a lot of stuff as NOS and it's not. You just have to do some digging.

The dealer does carry them but they regard them rather highly so I am shopping for a more reasonable deal.
