Ok,This doesn't make sense, so i have to ask....On a model 20 rearend...WHY the heck are the axles different length, from posi and non posi ? I was just told by a MUCH MORE knowledgible AMCer than me, that this was true. What the HE$%^^%$?? Guess i'm just used to messing with old 9" ford rear ends for years.They are sturdy and simple!! I had just bought a nice used twin grip unit and 3:54 gears to put in a 69 Javelin axle assy that "WAS" going to go into my 72 Gremlin. I've had the axle assy for awhile.Any one want to buy it??...3:54 gears also. I'll probably look for a 9" or Mopar 8 3/4. Thanks to anyone who can make sense of this, Joe _______________________________ Do you Yahoo!? Declare Yourself - Register online to vote today! http://vote.yahoo.com
