Mopar syas the new Alum is 10%? stronger then stock. There has been a new one on ebay for the past few weeks in the $4K range. Decades back before Mopar finally got around to offering an alum solution, I negotiated a deal to buy an entire rolling dragster with a MW alum 8.75, just to get the rear end.. Seller eventually felt sorry for me and just sold the rear, which I have today. I have a few Mopar alum rears, and a new one in the boX. The rears wiill not accept anything lower then 3.23 w//o some internal clearancing. When I saw the new $4K street price, I hesitated.

If you found a good/new unit for $1K, I suggest buy it, if only for investment, as they are never going to make more. twocents.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
