Have a dana 60 (I think) on my 81 F350. The steel vent line that holds down the brake distribution block to the rear axle found itself in 2 pieces. The local parts store couldn't find a match. Ideas on a part number? I managed to get the part that broke off the rear axle out and it appears to be 7/16 x 20 threads....

 

It's just a hollow bolt with a nipple made onto the end correct? Just trying to make sure we are talking about the same thing. I have never had to buy one before, but the Help! section in the store would be the first place to look.

Here's one for a 9 inch rear that has the same thread count.

I bought mine at the local hardware store

 

After further research, I found a part number and item description. Of course They no longer make the part new from Ford, but Uhaul (?!) has a lot in their inventory listed on Ebay :Ford Rear Axle Vent E7TZ4022A | eBay. I think the one Franklin2 listed would work too.....

 

Jeff's bronco graveyard makes them.
