If memory serves (and it usually doesn't!), the driver's side axle is 1" longer than the passenger side axle on the 70 and later rearends. There has been no difference in axle lengths in any AMC rearend that I have swapped to posi from non-posi. I think that either you or he had a miscommunication.?. Trust me when I tell you that you can put that posi unit and gears into your Gremmie with NO PROBLEMS, provided it is an AMC 20 in it now. The AMC 20 is a great rearend, and absolutely bulletproof with 1-peice axles. The "other" voice of experience Todd Aint it the truth as i have a 69 AMX model 20 in the ass end of my 73 Gremlin,its axle tubes were welded and it has Moser one piece axles and never had a problem when it was under the rear of my friends 74 Gremlin that was running consistant 10.40 passes in the Quarter mile.
