Bleeding the brakes on my '57 F100 with '80 Camaro clip, come to find the mast cyl needs replacing from sittin too long. Not entirely sure if it's a Camaro the mast cyl came from, part # on the bottom is 5488115. Did a net search, but nothin turned up. Always worth asking here. Previous owners put late model front end and parts into this frame, owned her for more than a decade and I'm still finding new info about it. Got bleeder screws today to replace the old ones in those Camaro calipers... standard or metric thread? Got a pair of both Justin Case. Glad I did: one side was metric, the other was standard.Tomorrow I'll replace the bleeder screws for the '72 Lincoln rear, just to be on the safe side.
Maybe a picture of your master cylinder will help, I know the 66 Mustang 1" bore ones were pretty common to use.
Thanks for the help, RK- what's interesting is that's the kind of truck her C6 came out of (again, having run the numbers). When I first got her, she had a mid-60's car FE with that shift-kit'ed '72 C6, Camaro clip, Mustang II floor shifter and gas pedal (pedal arm of course kept tweakin out), 70s Eldorado tilt-column steering bunched WAY close to the steering box. Ohhh dear. heh heh
