Hello all. I am looking for some info related to the Clutch master output fitting. I am running a LM7 adapted to a SM465 and with the swap I need to run a hydraulic throwout bearing.

That said I am trying to find a adapter fitting out of the clutch master to a male -4an fitting but locally I cant find anyone that can match up the fitting. Appears to be about 7/16 in diameter but its a deeper bore than a typical brake line inverted flare type fitting.

Anyone have any ideas or suggestions?

Fitting size on master cyl is metric M12x1.00. I used a 3AN line for my clutch. Bought my fitting from summit racing I think.
