1966 C20 Rear brake line tee fitting

[plmadding]

Gents,

I have struggled with this for too long now! I need some help.

The rear tee on the C20 seems to be unique. I cannot find a replacement for it online. I mangled the threads and I don't know what to do now.

I think my first step will be to try and clean up the threads. The fitting will not screw in far enough to seal.

The angles required to bend in this box attached to the axel are not fun! It is a real challenge. If I cannot clean up the threads enough, what are your suggestions on a solution?

Thank you!
