Finally, my ISP is working;
For those who care and I guess those who don't, GM always called theirs' a
*POSI* unit, Ford *LS* limited-slip and CC *Sure-Grip* and I guess it just
carried over, even though DANA builds most of the rearends for all three
(now). Although I will have to admit that this Dakota unit seems to be
stronger than the Ferds I have had recently, but I guess that is due to OEM
specs to which each is built.
BTW, somewhere in my '97 literature I saw "Sure-Grip", but my brochure says
limited-slip, the window sticker says Anti-spin, so I guess it all "means"
the same, except for the one in my *Hemi* car, i.e. Dana 60, now that's a
Sure-Grip!!!!!!!!!!
That-aaat's all folks.
