does anyone know what size threads the lines going to the master cylinder are? this is a 94 trans am but it may have an ls1 master, im unsure if they use the same threads, ive read somewhere its like an M11 but i cant seem to find any info on it. guy at the shop is trying to get me to pickup car but i need this done first.

 

They are an 11mm x1.25 I believe.
I'm positive on the 11mm part, not sure on the pitch.

 

as an update, i ended up buying an abs block , lines, master, reservoir, and booster assembly off a scrapper car for 35 bucks.

only needed the two fittings lol.
