Re: AC Delco Part Number for Left Rear Flexable Disk Brake Line
Before you buy anything, I'd suggest you look at what's on your car now, because the factory rear disc brakes with iron calipers, like your 85 and my 87, don't use a rubber hose on the left rear.
It uses only a hard line that runs all the way from the Tee to the caliper, and it's coiled (hence the description "flexible line") where it connects to the caliper. There's no rubber hose like the passenger side uses.
If you're upgrading to newer style rear brakes, then you'd need a hardline for 89 and the suggested rubber hose. But if not doing such an upgrade, then chances are the existing coiled hard line doesn't need to be replaced.
