Brake line adaptor fitting recommendations

[ktneifert09]

I bought a set of brake lines from somebody a while ago (can't even remember how long) and all the fittings on them are 3/8 inch.  Of course only two of the fittings on the distribution block are 3/8 there are two that are 7/16 and one that is 1/2.  To top this all off, the lines out of my power brake assembly - one is 1/2 and one is 9/16.  So I guess I either need to re-do the ends of some of my tubes or get some adaptors.  Any advice on where to get adaptors?  Is this an ok thing to do - I know it's not stock but I'm just building a daily driver for God's sake.

I believe all the lines have to be the same size

Adapters should be available at any good auto parts store.

I had the same problem. I found master cylinder adaptors at Carquest in their drawer cabinet holding brass fittings
