For the early XJ's (PRE-90):

What is the bolt size for the rear brakeline to axle?

Thread diameter/pitch would be awesome. Don't need head size.

I would check but BOTH my XJ's are POST-90's

Need this info so I can make a new extender for a members XJ.

Up until 89, the axle breather was separate from the brakeline mounting bolt.

Whereas 90-newer, used a mounting bolt with the breather tube built-in.

Need bolt measurements for IMAGE #1

 

Here's a picture of said bolt in question, next to a tape measure. All pictures were taken from DIRECTLY above.
