I just got my dads 94 c1500 with the 4.3. It needs new rear break lines. But i cant seem to find a definitive answer on what break lines from front to rear and what fittings it needs. On know that the 1/4 line i bought is smaller then the line from the front to the rear. Any help would be appreciated. Right now im just getting it back on the road so not going fancy just making my lines. Thank you
