Rear brake tubes are rusted out on my 94 80 series w/abs. Discontinued from Toyota and have had zero luck finding any. Part numbers 47234-60210 and 47362-60050, these are the long ones that run along inside the frame from the front back to the LSPV. Dreading the thought of making replacements and wondering if anyone had any ideas or knew of anyone who might have new ones available. Any experiences or wisdom would be appreciated! Thanks!
