I have a 1967 M-715 dana 60 front as you all know, Am I looking getting a locker for the front, Am I right saying I need a 30 Spline, full floating, 456 and up carrier when i order one??????? Is there anything else I need to know. I have put a locker in my model 30 on my little jeep is it pretty much the same deal?? Was thinking about going with lockright, does anyone have any bad things to say about them, I do all offroading in it. I know they make better lockers but price does matter in my build but ohh well thanks for any info.
