I need master cylinder fitting

I think this is the fitting you are looking for. I had to get one for my Wilwood MC. Actually I had to buy a package of four since that is the only way they would sell them. I think it was Autozone if I'm not mistaken. If you can't find one PM me your address and I can drop one in the mail for you.

Thanks for the info. Original 1975 dual M/C had 9/16-20 threads for front fitting. Of coarse I had pre-made lines with 9/16-20 ready to go. Had an extra 9/16-20 fitting also. Replacement M/C had 9/16-18. NAPA fixed me up with 9/16-18 adapter to use with 3/16 fitting. Switched pre-bent line to 3/16 fitting. So that was okay, but the actual correct fitting looks better. Don't know when they switched thread sizes.

Took this photo info to Auto Zone. Of coarse the blister pack spot was empty. <$5 for 4. Should have first thing today.
