Yeah - I know all that guys.
If these things were not in near-perfect condition, I would not consider using them.
68/beeper - don't forget that I live in the land of gouge pricing and taxes - nothing is cheap here...especially parts for 30 year old cars. Best price I have found for a prebent rear axle line kit is $49.00. (Not including the rubber hose that goes between the block and body hard-line.) I would consider bending my own from generic lengths, but finding those to fit is easier said than done. I'm not experienced enough with a flaring tool to feel comfortable with "do it yourself" lines...not an area I want to practice & learn on....
As it stands, I have to replace the hard line from front - to back ($94.00) because I broke it dis-assembling the car, and all of the front lines and hoses to accomodate the disc brake swap. ($130.00)
Anyways - I've inspected the rear axle lines closely, and other than being dirty from axle grease, they seem to be in pretty good shape - not even external rust. I'm going to clean them up and if I find any other issues then I will replace them.
Thanks fellas.
