I'm looking at a SAS for an 88 ranger. Right now I have the d28/7.5 combo. I found a Jeep comanche in the junkyard that has both axles in excellent condition. I know it has a d35 rear and d30 front. If I want to run 33's, with these axles handle it? Also, if I do an engine swap later on, will they handle the increased power?
