This is the precise reason I plan to swap in a GMT-400 era 10-bolt. They are a little bit wider than the 10-bolt used in Squares, and are 30 spline instead of 28 spline (so a little stronger).

It would make more sense to do the 14 bolt semi-floater from a 2wd light duty 3/4 ton truck. Then just have the axles and drums re-drilled for the 5-lug pattern. Or buy replacement axles and drums for a 454 SS truck.

*The 454 SS rear axle would be simpler, but good luck finding one for a decent price.

That would probably work, but I'd prefer to keep everything to the point where I can use as many factory parts as possible for ease of repair. The 30-spline 8.5" 10-bolt is pretty strong anyway (pretty much as strong as the truck 12-bolts are, lots of mis-information about this out there though). I plan on adding some aftermarket axles, an Eaton 30-spline posi, a girdle cover (keeps the bearing caps under tension to prevent flex), and a solid pinion spacer (prevents the pinion from walking away from the ring gear under load). It should be as strong as I'll need for the power levels I am planning.
