3.42 SRW to DRW Setup

I know this has been posted about before, but i'm looking to do some trading.

I have a 3.42 SRW rear axle and am looking for a 3.73 or 4.10 DRW FRONT AND REAR. I can run with a 3.42 DRW axle if you dont want to swap fronts but would prefer a shorter gear for a little more towing capacity. My truck has 204k on the clock, but the rear axle went thru a complete rebuilt 20k miles ago (last October) by a stealership. Truck is a mega cab so if anyone has a use for a mega cab bed, it'll be up for sale as well after the swap.

Anyone interested, let me know. Wanting to try and do this between December and March as we wont be hauling the rocket donkey trailer much.

Thanks.

Anyone have a 3.42 DRW axle w/o air suspension that they'd be willing to part with?

OR... any DRW axle that they'd be willing to sell that would work with a 2015? I can swap centers out whether it be front or back. Would prefer to run up to a 3:73 or 4:10 anyway.
