Can any one tell me what size the brake line fitting is that gose into the caliper on the front axel of a wide track dana 44. Thank you in advance Jim Aka Wilseya

It is a hollow 7/16 bolt.

Yep those banjo bolts are 7/16" Jim. If you can't find them listed for your axle application look for bolts for a '78 Chevy 1/2 ton 4x4. They have the same calipers.
