96 Blazer ABS Does not work....

Hi guys, new here, anyway, for the past year or so, The ABS light has been on, so I brought it into school and put our scan tool on it. It gave me codes c1267 and c1270 or maybe it was C1269 also? uck can't remember... I know 1267 is a RR Inlet Solenoid Malfunction, but I'm striking out on 1270. I replaced the booster as that also blew out, and the rear drums and I did the front last november. So I need some help, If there are any GM techs out there please chime in...Oh, and ah anyone know where I can snag some oil cooler lines? They're starting to leak... and I don't want those blowing out.. :banghead: :banghead: :banghead:
