Hey guys. dont know a whole lot here. Just wondering if there is an axle that will direct swap in to my 1980 bronco that had factory 4.10 gears. i dont have a bunch of money to pay for gears but have a TON of junkyards around me that may have what i need. i know i can use the d50 with 4.10s in the front but not sure what is available in 5 lug for out back. thanks guys
like Steves pic showed, code H5 if you are looking through junkyards.
4.10 rear, 4.09 in front is what I have.
h5 is just a limited slip with 4.10s in the rear axle

1 = 3.07 (heavy), 3.00 (light), 3.54, 3.07
2 = 2.73, 3.73 (early light), 3.50 (early heavy)
3 = 3.54 (late), 3.73 (early), 4.10, 4.11
4 = 3.00 or 3.73
5 = 4.10
6 = 3.55 (heavy) or 3.73 (medium)
7 = 2.47
8 = 3.08
9 = 3.55, 3.70 or 4.11 (early)
3rd digit: Any character (usually 2 or B) indicates a limited slip front axle (4WD)
8.8" axles under fullsize light trucks are rated at 3800 lbs or more.
so 15 or 19 would be acceptable, but always check tag on cover and stamping on ring gear
i know i couldnt find any 4.10 axles out of the 20 trucks i searched at the JY. 3.73 was closest ive seen and 3.55 is defiantly msot common. i couldnt even find a 4.10 Sterling axle (or at least a good condition one) and i had to use a D60 from a E-250 van. even using carpart.com the closest 4.10 8.8 axle to me was over 275 miles away
