Anyone know what size for MC these are for 67 charger?

[Jamesjames]

I’m trying to buy some adapters so I can use my 3/16 brake line. I can’t find what size these are. I think the front is 1/2 and rear is 9/16 but I am not sure. This is a standard MC for a 67 charger. Thx.

They are 1/2" 20 and 9/16" 20. You can buy the nuts for 3/16" tubing, from inline tube and ebay etc. It would look cleaner than using adapters. Keep in mind that 9/16" 20 is an odd thread, so make sure it is right, if you are going the adapter route.

I second buying from inline tubing
They have reasonable prices and ship fast
If it was me I would buy the two lines with the proper nuts and change them
another option is buying a complete kit and changing all of the 54 year old lines

1/2-20 and 9/16-20 as stated previously. Don't buy a rebuilt master, rockauto.com has them new for $30

I'm sorry you are having trouble
Everything I have bought from them has worked wonderfully
Did you call their customer service?
