WTT or WTB:14-bolt/4.10 for my 3.73

[special-K]

Here it is...
My`92 K3500 SRW has 4.10s and there`s a problem with the rear.I have the 3.73 rear from my`95 that I totalled that I`m ready to install and change-out the gears from the 4.10.I`m wondering if there`s someone within striking distance with a truck or just a rear with 4.10s that might be considering going to 3.73s.I`d swap 3.73s into my front,but I think I need to stay with what I have for my marine-prepped 6.5TD to run right.It likes higher rpms with no wastegate and a higher output injector pump(& medium duty turbo).I also run 255/85s which are about 33 inches tall in a heavy truck(Reading work topper full of tools inside and out).She blows the black smoke below 2,000 rpm.So,that`s where I`m at and why I need to swap.The 3.73 rear from the`95 has 120,000 miles and was in a truck that I bought used @ 50,000 miles and babied.I garauntee there will be no problems with this rear.I`ll be putting it in my`92 if I find no takers or a deal on a 4.10.
Prolly a pm would be best since I may not check here too often...Thanks
