With the auctions on EBAY for a complete rear axle assembly and a complete front axle/differential, I am now contemplating purchasing both, then replacing the drive gears to a numerically higher ratio...Hnce, my post and question. Is the drive gears in the SRTGC standard MOPAR parts, so I can buy the higher ratio, or perhaps is it a DMX/Benz bastardation. Any thoughts?
