Gear upgrade advice on 7.25 axle with 2:76 gears

Way back in the late 90s and early 2000s, I blew 6 7-1/4" axles with Slant Sixes. Now my Slants were tuned up a bit, lots of hard accelerations, and my 904's had the Mopar magazine shift improver mods, like a 3.8 kickdown lever, higher line pressure, a few valve body separator plate holes drilled out, etc. On the average, they lasted 5000 miles, but one hung in there under my lead foot for 41,000 miles! They failed in different ways. Broken gear teeth, stripped side gears, failed wheel bearings, etc. I never rebuilt one, I'd just swap in another axle assembly.

My suggestion is to pay the cost of an 8-1/4", rebuild it how you want it, and never have an axle problem again. If (and probably WHEN) I blow my 7-1/4", I'll assemble an 8-1/4" with a sure grip I will rebuild, and 2.94 gears.
