Hi. Can someone please tell me the correct bolt size that attaches the brake line distribution block to the top of the Dana axle?
Thanks much

7/16-20 and it was a vent not a bolt

Hi Vance. This is Paul Saccone. You did the body/paint on my FY1 440 convertible 10 years ago. I'm still slowly putting it together (should have had you do the whole thing!!).

Wish I could remember....so does the brake block attach to the rear through that vent hole (it looks threaded). Is this a special bolt.

Thanks for your feedback.

Special bolt with loose fitting vent cap on it's top.

Where may I find one to purchase?

Junkyard, car, van or truck with it in it will work as long as it comes off of a Dana 60 Some of the 4whd trucks have a hose on them, that extends way above the rear end housing up into the frame to keep water out of the housing

Thanks

If you aren't sure on anything diff related, you can't go wrong with Cass/DrDiff.

Last question for now - is there a washer between the vent bolt head and the brake distribution block?

Yes, it's an external-tooth star washer.

Great....any idea where I can buy one? Thanks

DrDiff did not list one....

You might give Cass a call, he has more than listed on the site from memory.
