Fabbing new rear axle lines is actually quite easy since they're relatively short and easily accesible. You probably can find an OE rubber hose to fit your needs, but it'll take a little digging to do so...you might have better luck with getting recommendations by posting up what you have with respect to length and fittings that you're trying to match. To the best of my knowledge, both the '78 Impala and mid-90's 9C1 used the same 7/16-24 female inverted flare fitting at the body end and a (2x) 3/8-24 female inverted flare tee fitting at the axle, but maybe not. In any event, it would help to know what you're trying to match explicitly rather than by application.



Assuming you can specify what you want with respect to fittings and length, you also have the option to go with an aftermarket braided stainless hose.
