i just picked up an integra rear disc converion from the junk yard.. problem is, i forgot to get the porportioning valves from the firewall.. the junk yard is about an hr away..

my question is.. am i okay running w/o the integra porportioning valves or do i really need them?? the yard that i bought the conversion from was kinda a d1ck about thiings because i wanted to buy 2 conversions and he only wanted to sell me one.. what an ***.. anyways... any advice would be appreciated from those who've done the swap...

thanks,
