check these guys out, just found them the other day and they have everything, even a 14mm 1.5 bubble flare union that i've been looking for for a couple months. Ordered monday and should have a bunch of parts tomorrow! seems like a great company

I have a 85 Z28 W/ factory front disc and drum rear...I recently bought a 9 bolt rear with PBR Discs. My prop valve is round shape and the rear brake line attaches to the front of it. Is this the standard double flare prop valve or did they make these metric too. I have one of those aluminium flat on both sides prop valves that came off a 91 and I'm not sure if my brake lines will match up to this prop valve. please advise

Thanks!!!

 

the roundish propvalves are SAE thread, so they would be inverted flare IIRC. The later ones are square machined pieces and are metric threaded with bubble flares

 

Thanks for the info!!!
