master cylinder to prop valve line trouble

[skeeterbug]

i hope one of my fellow board members can help with a very aggravating problem i am having with my 4 power disc conversion i am attemting to finish up. i am currently converting my 71 lwb over from manual disk/drum to 4 wheel power disc using captn fabs astro van disc conversion brackets for the rear, very good quality stuff by the way. i have everything done except i keep having trouble with getting the right steel lines that go between the master cylinder and the prop valve. i bought a master cylinder/booster set for a 88 s10 from orielys, the prop valve came from jegs a disc/disc valve. all i guess i want to know is can i use my corvette style master cylinder w/ an 88 style s10 booster, the master cylinder it came with will not work with any of my steel lines i have like three new set none will work with that style master cylinder!
